You may be talking about my experience, where I knew clearly from a long trend that the author was using "PG" when there was no pairing or a het pairing, and "PG-13 for slash" when there was any kind of m/m romantic relationship even vaguely implied. It started to grate after a dozen or so, so I quietly sent her a message and she replied thoughtfully and has not done it any more.
