The hand is to the inside of the ball at the instant of release. The ball is rolling off the area of the palm between the index finger and the thumb.
She is leaning WAY to the right to allow the hand to 'cut' to the side of the ball thereby giving it even MORE side spin.
Her palm is facing almost perfectly up at the instant of release, however, by cutting her hand hard to the left and up will give the ball a 'down and in' spin axis.
She is either throwing a down and in dropball or she is trying to throw a true cutter that has more drop spin than side spin.
