Looks like the forced hello elbow is actually helping propel her forward more at the end.
Just tell her that she does not need to come up with her elbow probably trying to please a coach or something she just heard once but stuck with her you can see see wants to follow through naturally.
She needs to stay open, the shoulders need be facing 3rd at release and hips can close after release and she is on the side of her pivot foot, needs to be up on her toes.
