I can provide (I hope) some clarification. This was a question raised at last years 18 Gold. A member of the national staff provided the following:

The ASA rule requires both feet in contact with the pitcher's plate at the time the pitch starts. The pitch starts when the hands separate. So long as the foot does not move forward, but only pivots on the toes, while not in contact with the pitcher's plate, is a legal delivery.

To the contrary, in NCAA, the rule requires half of the pivot foot on the top surface of the pitcher's plate. This would virtually keep the foot in contact, or very close to, the pitcher's plate prior to the drag.
