That makes sense. But at night that makes it point topside at moon? Which is basically "constantly tilted" of the moon is low?
(I read the article, but admittedly quickly, should probably read again)
What I understood was, it's not really about the moon at all, just that "the sky" is lighter than "the ground", and roughly orienting based on that works as a heuristic. Light & dark hemispheres, not the brightest spot.
