I wanted to add to this. Yes, this is a valid forehand obviously.
A great way to apply it is to use it on your approaches. when I am running towards a short ball I already am in the infamous PTD position like this guy. It has resulted in a noticeable improvement in consistent put away shots.
I also think the modern tennis game is just as much about the shortened take back as anything else. So you will see more players doing unorthodox things like this player, and yet still hitting big shots. Power = timing, and the shorter your take back, the easier it is to hit with consistent timing.
As for the dangling off hand, not sure if that is optimal. I know it would not work for me, but his balance is excellent and he has high athleticism.
