He certainly had the Ernest Jones-ish swinging motion along with a nice weight shift back and forth.
Probably more across the line than laid off as well. He might have had a more pop-out move than suck in move, but, hey, he's gone and we're not going to argue the results.
All in all, I'd agree more SD than anything else we've seen so far.
I see Zero pop out in his action. Check the youtube swing in the referenced thread
