I have no idea. All I know is that the NCAA men's and women's coaches who write the rules have no reason or incentive to care what the other side does. And since college officials almost never cross between the two that isn't something they have to worry about, either.

Interestingly I believe the other NCAA sports do use the same rules for men and women (except lacrosse because M/W lacrosse are two almost entirely different games).
