Complicated explanation if I have it right: 1. The girl enters into the motion as if she's kicking towards the back of the head, grabbing the assailant's right punching arm (who never should have been extending his punch that far out to the side in the first place).
2. The girl then levers herself up against that (mysteriously) solid arm to kick one foot over the assailant's head, while the other leg is moving to meet it. This is the point where she starts to twist the assailant's body towards his right, starting the motion. During that time, she keeps one hand firmly locked with the assailant's hand, creating an armbar, which locks the wrist and prevents the assailant from backing out of the twist.
3. The girl crosses her ankles to form a solid lock, bracketing the man. She starts to twist her body, extending her free arm to add additional momentum to her rotation Note at this point, if properly constructed, you've now locked the opponent into a solid frame of motion.
4. As her body crosses around to the other side, the body of the assailant, already in motion and locked into position, continues on his path of motion, which is twisting back and away. Remember, his wrist is secured so he can't just back away - at least, not without injuring himself.
5. The girl flips enough to face towards the ground. Given that the girl has locked her opponent into the position, he ends up following along, flipping and ending up prone on his back.
