I believe the rule is (substantially) the same (and I know the NCAAM rule is the same as the NCAAW rule), but I think NCAAM have interpreted "normal throwing motion..." as requiring "upward movement."

from the NCAA book:

Section 8. Continuous Motion
Continuous motion applies to a try for field goal or free throw, but shall have
no significance unless there is a foul by the defense during the interval that
begins when the normal throwing movement starts a try or with the touching
on a tap and ends when the ball is clearly in flight.

Not really. The NCAA requires "upward motion" to be considered in the act of shooting.
