I agree with the above EXCEPT the hand position. I think her hand position is appropriate for the horse. YOu don't lower a horse' head by lowering your hands. The horse lowers his head, THEN you lower your hands.
She is maintainging a pretty good line to the bit, whatever the horse does with his head, and for a horse coming back into riding, this is great.
People who lower their hands way down onto te horse's neck trying to "pull' him down are doing one of my pet peeves.
