That, obviously, is correct. However, the remote ip in this case is your local IP, so you are still getting a path to the destination. Even more importantly, LSR relies on every router on a forward path between <your-local-ip> and <remote-router-before-host> allowing LSR, which is an invalid assumption. Thanks, Alex
