That's the issue people have, you can do all that, why not be able to cut him off? Repositioning can result in a move being cut off, if done right. It comes off as, to some, that if they see an opening to stop their opponent, they have to ignore it - even if it can win the match for them, instead having to react to what's happening in its entirety, when it most cases - it wouldn't happen like that. Fighters, I believe, are trained to take the opening(except in professional wrestling), and that's implied here.

They, I believe, get that they can do anything - they don't like not being able to stop it if the chance is obviously there.
