Lots of 2hbh have no loop on the backswing whatsoever. It's OK and quicker to the ball.
Her dropped racketface might have to do with a strong switched eBACKhanded left hand, or a strong grip right handed. Most 2hbh use conti left hand, and eastern backhand lefty forehand. That limits the racketface drop and allows a sliced 1hbh conti backhand for low and wide balls.
