Captures cannot be undone either, but yes, that might be a problem. Go solves it with the ko/superko rule that states it is illegal to move in such a way to reproduce a previous configuration of the board, and I think the same rule would be relevant here. Edit: another simple solution (with interesting strategic implications) could be to forbid moving the same piece twice in a row.
