Sport Pilot, perhaps you should read it again. Does it matter if it was a go-around or a low pass? Not really. If there is an airplane in the immediate area, you need to land. That is the take home message. Any time there is a full scale plane in the area, you never know the intention of the pilot, or what might happen to him, so you need to clear the area. It is plain and simple, they have the right of way.
There is no rule that the RC plane land just because there is a FS plane 500 feet above him. It only says give right of way. That said model RC aircraft and FS aircraft have operated safely at a distance a lot closer than 500 feet.
