Roy oswalt's arm action

i am trying to gain velocity and oswalt’s arm action is really nice. i had a few questions about it.

1.) when he breaks his hands, does he swing his arm to that postiton behind his back, or does he shoot it right to that behaind the back poosition, i can’t really tell in his pitching clips, i think he swings it, just double checkin

2.) does he reverse rotate his shoulders, it doesn’t realy look like he is

i know this is a weird question, i can’t really word it right :roll:
