She has too big of a lateral move because she has swayed off the ball. Even if you use the base of the neck as your pivot point (like i do) you are allowed "some" head movement as long as the base of the neck stays in relatively the same place. Her's moves a lot.

Exactly what I thought. My conclusion was that if she moved the ball up she would not have to "reach back". That's why I started to think about ball position.
