This is kind of a variation of the standard roll-over, except starting from the leading side of the ball, the shot starts from the middle axis of the ball. When the man comes around and strikes the ball, the man has still rotated only slightly less than 360 degrees by striking the back of the ball. However, the fact that the handle is released completely does run the risk of letting go for too long and rotating for more than 360 degrees after striking the ball. the roll-over gets around this by ending up in the shooters knuckle and avoids the problem of rotating more than 360 degrees after striking the ball.
