It is not obvious to me that any twist in a maximally distant state
brings you closer to the home position. How do you know there
aren't two equally distant states that are a qtw apart? There is
probably a parity argument that proves this can't be so, but if you
count half-twists as single operations I'd be much surprised if you
could find a simple proof.
