Every rule set I am familiar with except NCAA requires the pitcher to start with the shoulders in line with 1st and 3rd base. The pitching rules in college are essentially the same as every other rule set, but for whatever reason they left out the portion I mentioned. From what I read, Auburn submitted video of her using that motion to the rules interpreter to make sure it was legal before she used it in a game.
That said does it not call the motion advocated by Bill Hillhouse into question? The shoulders certainly are not aligned with 1st and 3rd at separation of the hands.
