I think they might mean moatside lane (next to the shakespeare), and windy gap as we know it isn't actually windy gap. What we refer to as windy gap (the path along by the river from prebends bridge to framwellgate bridge) is actually called "broken walls walk" or something like that (check it up on the maps). Windy gap is the small alley next to the law library which leads down to that path.
Random i know, but what the hell.
