Hey Matt.....I shoot 3D sometimes with a guy who's REALLY proud of the fact that he's shooting 80#'s. He's a "sky-er" that's probably nationally ranked, himself, in the sky-ing dept.
THE only reason I try to do it the way I do.....is I feel like it's less movement this way, on stand. It makes sense in my head to go ahead and put my "pin" (sight housing) on my target early....and draw straight back. Once you get to the point of drawing back in your shot sequence.....I "hope" my form looks similar to yours.
Good point on the movement. White might work just fine on the range doesn't always work well in the woods. I know I wouldn't want to sky my bow as I drew it in the woods. Even on the target range, I feel like holding straight out and drawing minimizes my bow arm/shoulder movement which to me can mean just the slightest less fatigue.
