Didn't look like he locked it out to me...but he wasn't too far off and I'm sure he could have since the lift went up pretty easy.
I'm not so sure what he was wearing would aid in a bench press, looked like more of a squat suit to me, with two straps going over his shoulders rather than anything to support his arms. Usually when guys are wearing those shirt/suits, their arms stick out like they're a walking zombie.
