I guess Vos would have just checked behind here...

TT-KK isn't putting any more money into the pot unless he improves on the river. As for AK not playing that way, I would almost certainly check for pot control if someone cold calls a 3bet and then continues on this board (aka "I have implied odds with my obvious pocket pair to hit a set. Oh lookie here, I now have a set) unless he is a loose donkish type.
