It looks to me as though she's still looking back in the general direction of the Texas School Book Depository in slightly blurry Z-207. Why do you ask?
Here she is in z145 followed by z200, then z206 and z207.

Do you not see a significant difference between z145 or z200 and z206 or z207? Here is a close-up between z202 and z206:

If you think her upper torso is twisted to the right in z145 you are not looking at what I am looking at for frame 145, which is this:
Her right arm is to the right and her left arm it across her midline but that is normal arm movement while running forward.
