That the NCAA apparently recognizes that, is only to be noted as evidence that the two starting positions can be considered as divergent.

My exhaustive explanation of the generally accepted differences of "kneeling - whether on one or both knees - and standing - whether on one or both feet" addresses your second point.

Can't have a case book play for everything. It would be thousands of pages and no one would ever read it.
