i think i read that in the book that comes with the Led Zeppelin Box set, and he did it because he could. Zeppelin also sort of had a thing for giving their songs titles that have nothing to do with the lyrics of the song. "Four Sticks" and "Black Dog" are two such songs (black dog was named after a stray dog that was hanging around the studio that they were recording that album at).
