I call that a shank slice, I've never found a more 'official' name for it. This type of motion will result in a ball that starts way right and goes farther right, just like you said. It is even theoretically possible to shank this kind of move because you will be leading the hosel into the ball.
Yeah, Trevino played a "shank slice?" Huh?
Ok maybe I wasn't clear enough. The dotted line in the diagram is your intended target line i.e. where you want the ball to start on it's flight. Body alignment doesn't come into a discusiion on ball flight laws. Granted when trying to achieve any of these flights you need to think about body alignment but the body has no impact on the fundamental laws of mechanics.
Body alignment absolutely comes into the discussion when talking about ball flight (not the "laws" themselves, but in ball flight). Pulls tend to go lower. Pushes tend to go higher.
If body alignment didn't come into play then EVERY good draw would be a push-draw and EVERY good fade would be a pull-fade.
