What is this diagram illustrating? Are those pictures views from one location at different times (and degrees) or from different locations on earth?
they are pictures from a single date and a single location arranged in a way that represents the passage of time between them. the observer was not located on the ecliptic equator.
it's consistent with a moon that orbits a spheroidal earth. the sky (a constant distance from the surface) is curved on a sphere - the moon has the same orientation ((minus slight precession)) from the POV of the center of its orbit, the center of the earth, not from the POV of an observer on the surface of earth.
so the angle changes a little according to your latitude and the radius of the earth.
nothing crazy like 90°
the universe does not revolve around you.
that's the geometric mistake you made.
Psalms 8:3-4
When I consider Your heavens,
the work of Your fingers,
the moon and the stars, which You have ordained,
what is man that You are mindful of him,
and the son of man that You visit him?
The scripture clearly tells us that rightly understanding the universe makes it obvious we are not the center of it. we are insignificant before it.
David can't write Psalm 8 if the earth is a snowglobe with the entire universe revolving around him. flat earth puffs up man's pride but the real universe utterly humbles him.
