After his visit to the lower river, 164 headed back up to the falls. He just thought he would confirm that is, indeed, 164 for anyone who wasn't completely sure. Very considerate of him to do that on his first day back. (Also I think he saw a fish jump and decided to slide on into the falls just in case.)
