I've looked at it again and again, experimenting myself with a cricket ball. I now think/believe that the index & middle fingers are playing a similar role to that of a fast bowlers grip. making the ball rotate towards the palm of the hand. The only difference is it's being forced to spin by clenching the index and middle fingers, running the tip of the fingers over the top of the ball. Now the rotation of the ball towards the batsmen only depends on hand position and what frame the ball comes out of the hand. This could have been anything from a type of half overspinning, to side spin, to half back spin delivery. I believe that from the momentum of the twisting wrist & angle of the wrist/hand and where the ball was released that it has come out as a sort of slight overspinning & mostly side spinning delivery, with the centre of rotation from the front of the ball(batsmen side) tilted a tiny bit down towards the ground(very slight flying saucer).
edit: another thing that can affect the angle of rotation is clenching one finger more than the other.
I need to put pictures up, or even demonstrate the wrist action on a recorded video because I am horrible at trying to explain things clearly.
