Like you, for me she goes clockwise but you can reverse her:

Stare at her left heel, the one that "hits" the "floor". Now look at the reflection of the foot as it hits the floor. "Make" it change direction. Imagine it goes counter clockwise. Soon it will. There is some kind of "jerk" in the image...when the loop starts again or maybe it is on purpose. That's where I can reverse it.

Now, while still concentrating on the "reflection" of her left heel, bring your focus out a bit until you see her leg swinging counter clockwise. If it is still going clockwise, look at only the reflection of her foot again. Keeping trying that until you get the leg swinging counter clockwise.

Ahhh. From right-brain to left brain. Like looking very closely for four years at Iraq. But it keeps switching back!
