Forget what we see the Moon doing from the perspective of the Earth...what matters is what is seen from the perspective of the Moon itself...the Moon sees a reoccurring and revolving sky pattern. That is spin.
So, Baz, the Moon is like your mobile phone traveling in an orbital path, and we, at the circle's centre, only get to see one side of the mobile phone, while the rest of the universe gets to see all sides of the mobile phone (Moon).
Like Parallel Transport.
