The tips from that website provided by (who was it?) helps quite a bit. Initially I could only get it going clockwise, despite following other tips here, but I managed to get it to go anti-clockwise after trying out those tips.
The trick is really where the legs cross each other. When they cross each other, they actually swap places.
Right leg turning, left leg standing - clockwise
(right leg crosses over)
Left leg turning, right leg standing - anticlockwise
(left leg crosses over)
Right leg turning, left leg standing - clockwise
I can almsot make it switch at will now by looking at her ass.
