He couldn't step away because Royce was holding him.
Just curious, because these last couple days every time I see your avatar I predict "ah, this dude is gonna shit on Ken again!" and I'm always right for now.
So 'fess up, is it because you're a Tank fan, a Gracie fan, or a Shamrock hater? ^^
Anyway
Yeah the low blow was blatantly obvious
(even more if you train, wore a cup and knows that it isn't a mawashi),
after that Ken had his "I got nut-shot" face and kept trying to grab his crotch and argued with the ref instead of trying to defend the TD and punches on the ground.
It wasn't like the Sakuraba fight in which Ken was clearly rocked and almost fell through the ropes with his eyes going "
" and then complained because fight stopped too early.... Ken often feels like he's been wronged
The second Tito fight as a bit early, but Ken couldn't improve his position anyway so watching it live I was content with the stoppage, don't want to see legends get beat up unnecessarily.
So, Royce cheated (not the first time, even if IMHO he didn't low blow Ken on purpose, just took advantage of it when it happened), and it warrants a NC and immediate rematch with a competent ref.
