The high kick (I assume you're talking about the one where they both do it at the same time) part, that's actually shows that while they are both kicks done while spinning around, they are of different styles (look at his final pose versus her final pose...different styles often share types of strikes, but the position of the rest of the body can differ quite a bit).
Really watch her fighting style. It has more in common with a Kung Fu style seen in films like Crouching Tiger Hidden Dragon than it does with the Monk style.
I think proclaiming that she is 100% a Monk right now, without further information or clarification, is simply premature, and conclusions that say she is a Monk are ignoring the aspects of her fighting style that don't match up with how Monks fight.
