Couple of things-
1- AAU Girls normally play by NCAA Women's rules. Perhaps that's what they meant or thought you were asking you you apporached them.
2- It's not uncommon, especially in AAU games when working 4-10 games per day, to not do a lot of switching, and to shorten the court as much as possible. Right or wrong, that's usually the way it is.
If you weren't critical or unhappy with their calls, why did any of this matter?
