Is this description correct of the Japanese jujitsu version of a RNC where you are standing behind your opponent:
  1. You start standing behind your opponent with one leg forward.
  2. Opposite arm goes around his neck with your thumb facing you. Try to trace around his neck with your thumb like the "off with your neck" motion. This helps you sneak your arm under his chin while staying close to his neck. Keep lots of pressure and do it quickly!
  3. Finish your motion with your elbow below his chin and the other two long sections of your arm pressing into his carotids. If you need to, grip the boney part of his opposite omoplata with your hand to secure your hold.
  4. Grip your hands together in a gable grip with your choking arm palm-down; the free arm's elbow stays low so he can't grip it. Or you can simply use the regular RNC grip behind his head.
  5. Pull him back into the hole behind him beside your extended leg while squeezing his neck. Keep his head horizontal to the ground while his back arches. CTFO
This is more of a move from self defense than sport technique, but I still want to document it. I believe it is called hada ka jime rather than ura eri jime. (What does ura eri mean anyway?)
 
"Ura eri" would translate to "rear collar".

Ura nage = Rear throw

Okuri eri jime = Sliding collar choke

what if your opponent has two legs? also wouldn't it be easier just to kick his leg away sending him crashing to the ground?

That's another possibility; although, I think it takes less energy to stomp on the back of his knee and choke him out.

that was my first thought too, what the fuck does standing behind your opponent with one leg mean?

Doh! I forgot "forward". So you have a kinda staggered stance with one leg forward and one leg backward. Like in the link except standing...
 
that knee in the back could probably hurt like a SOB aswell, but do you guys think you have enoug control over the attacker that way? I mean there is plenty of romm moving to the sides and a closer contact with your whole upper body would be better?

I don't know if real life. I do know you in practice should switch to a staggered stance because (1) it lets your be stable in the motion you are pulling hip (2) it makes your most stable direction perpendicular to his most stable direction. This way he can't back up and push both of you down, or lower his hips and koshiwaza you into the pavement. It also makes a space you can pull him backwards into - destabilizing him - while remaining stable yourself. However, this is all theoretical. Perhaps one of the judoka or aikidoka on this forum could help me out/confirm this.

This is similar to how its taught in the military. You begin behind your opponent by grabbing his shoulders and pulling him backwards as you kick the back of his knee with the instep of your boot/shoe. You then encirlce the choking arm around his neck(much like described above) preferably using the arm that is opposite your secondary weapon(pistol) to choke. You then lock the standard RNC grip(hand on biceps or shoulder and hammer fist behind the head) and strangle the victim while pulling him backwards and keeping the thigh of your forward leg in his tailbone to keep him off balance.

The staggered stance with your body turned sideways keeps him form ippon seoi-nage'ing you over his shoulder which is the most common counter to a weak RNC.

Also, do aikidoka even do RNCs or counter them? I didnt think it was in their repertoire of attacks or defenses?

Bingo, if you put a shitty standing RNC on me, i'll just throw yours ass through the floor.
 
The way we do it is, pull back on their forehead and shoot your hand through striking their neck with your bicep to get your arm very deep, reach through grab your bicep, and then slide your hand off their forehead to the back of their head and lay back with hooks in and squeeze
 
It's a pretty decent description.

I would consider adding a note on head placement in relation to protecting yourself from a backwards head butt from the person you're trying to strangle. (See attached picture - It's from a self defense seminar give by Phil Porter)

Off balancing your opponent and keeping them off balanced should be a focal point in my opinion. If I were writing a description on how to apply a RNC from a self defense point of view, I would probably have a stronger emphasis on it.

Generally for formal demonstration we present our side to ukes back. We use the tips of our rear hand in the small of ukes back as we off balance them with our front hand. Then we slide it around their neck as you described in your post before removing our rear hand from their back and taking the grip you see in the attached picture.
 
I learned Hadaka Jime Ichi from standing on one knee behind an opponent sitting on his ankles. Your description is excellent when it includes the encircling of the thumb, but your other hand not only completes the gable grip but is also used to focus the strangulation. You are describing modified/reinforced Hadaka jime or Hadaka Jime ni (#2). I would also add the positioning of the radius of the wrist on your hand touching your uke's throat being just below the adam's apple and also the flexing the wrist to complete the choke before pulling it back into the throat.
 
you also would use your head and shoulder to trap his head and shoulder so that he has no slack to escape and less slack to breathe
