Sure are many wonderful things going on here in her Anna's pitching, but the HE-style of pitching ain't one of them.
Maybe it is all a matter of definition.
I'm having difficulty in putting IR with "the whip" and then claiming 80% of the throwing motion is IR. Kind of like saying, "Me and Tiger Woods combined to make $9,000,00 last year."
Here is Anna Miller from Upstate South Carolina (pitching starts around 1 min):

Clearly, she is using an HE. However, her whip is good and she has good lower body mechanics. She hasn't lost 80% of her pitching power because she is using HE.
BUT (and there is always a but) when she starts trying to throw an IR drop curve (around 6:55), it seems she has more pop on the ball than she does with her fastball.
How about a change up?
My favorite line that I hear is "Wow...your daughter throws the ball hard....but work on her finishing (textbook HE finish demonstrated) and she'll be unhittable" I just thank them and tell them "We'll work on it"
