If hero is correct in how villian is playing, then I certainly woulden't 4bet/re-evaluate fold to a 5bet shove or whatever, if that's what you mean by re-evaluate I'd be happy getting it in vs this sort of player. If he has it this time, then good on him, but more times than not you're massively +EV to get it in, even 200BB deep as a huge favorite.
Also, because it's like a CO/BTN battle, he might have hands like A,J+ which are willing to 5bet/stack as he might think you are playing back or whatever the reason.
