While sitting at your desk, lift your right foot off the floor and make clockwise circles.now Draw the number "6" in the air with your right hand. Your foot will change direction and there's nothing you can do about it.
I did manage to stop the foot reversal by slowing right down, like Meindzai said, but the first time I tried I didn't even notice my foot has changed direction until afterwards.
This thing about independence of finger and thumb, though ... no problem.
Years of playing musical instruments is the most likely reason, which leads me to wonder whether a kit drummer would have any difficulty with the OP task.
Or a dancer.
