The relay has a detent for the lock position. The door latch is locked rearward. So in order to have the relay strap in the recess on the door and the relay detent to match the latch lock position, you have to switch sides with the relays. If you wanted the door handle down on the door, you would have to push forward to open the door. That seem backwards to me, handle up is more normal ergonomic to me. Either way the relays have to be switched to get the lever and strap in the door recess channel.
