Hello Per,

I think what Andrei tried to say is that there are Chess960 begin
positions which, after a few moves, are reached with the opposite side to
move. Simple example:

1. Sa3 Sa6 2. Sb3 Sb8 3. Rc1 Sa6 4. Rb1 Sb8 5. Ra1 Sa6 6. Sb1 Sb8 7. Sc1
and the beginposition is reached with the other side to move.
