Legal pitch?

6.3-I says she can slide or turn the pivot foot as long as it maintains contact (part two of NCAA rule difference above). But, she hasn't turned nor slid (slided?) the foot, it's in the same place.

And that's why I reject 6.3-J for this slide. She's still in the same place, albeit not maintaining contact. This part of the rule doesn't specify maintaining contact, just not pushing from another "place".

Let's be honest. The NCAA rule incorporates an interpretation of actions that they judge don't gain an advantage. I'm not looking to nitpick something that isn't clearly stated to be illegal (when it easily could be, like stated in maintaining contact when sliding or turning the foot) when there is no apparent advantage, AND it's clearly stated to be legal in another major (read the big three, NCAA/ASA/NFHS) ruleset.
