"Orbit" is ambiguous. Do you mean the sidereal period or the synodic period? They are two different definitions of the word orbit.
not to get bogged down in word games, but the moon "appears" to rotate exactly once in the time it circles the earth. now since the earth has circled the sun a good bit, the moon must have moved a little bit more. These are facts that everyone knows, but hardly thinks of. not everyone knows what "sidereal period or the synodic period" are. the discussion was about what everyone knew or didnt know.

the more man learns, the more he realises, he really does not know anything.
