The rear slip isn't dangerous in itself it's just hard for most mortals to counter as well as Floyd does.
IF you keep rear slipping too often just like any other slip your opponent will be able to time where you head is going to be. With a rear slip that's quite easy to do because all they have to do is move their feet up on you and keep punching down the pipe. This is what Barrera did to another famous exponent of the rear slip, Naseem Hamed.
I also agree, but the "rear slip" is much easier to time, and defeat. When a slip is performed to the side, you are able to angle off, you can pivot or step off to the sides easier. When you pull back, you can only continue to move straight back or come forward. When somebody decides to come forward and you can only move straight back, that is where you get caught. But you pretty much said the exact same thing.
I am a boxer first, I always taught to never pull back, obviously in the heat of battle, you do, and it does work from time to time. I won't lie, but it only takes one time, and it will be over in a second. The point I am trying to make is this, even though you are good enough to get away with bad habits, if you can avoid doing them, you should, because one day you may not be so lucky. But people like mayweather, ali, roy jones jr. anderson etc.. are so good that it may not matter to guys like them, but it will to anybody else.
