I've watched the first 17 minutes so far before I had to stop. It seems to be a good job at illustrating what the paper is trying to describe. Please do not take my criticism the wrong way.
Movies starts off with examples that are clearly close range, and therefore subject to significant perspective effects.
Model from video:
I may be mistaken, and someone please correct me if I am to be wrong, but this seems to be a bit out of proportion.
Distance from earth to sun: 92,960,000 mi
Distance from earth to moon: 238,900 mi
If we imagine that line growing outwards from the earth to the sun growing and the distance to the moon shrinking, we can visualize that if the proportions changed in that manner the phase would point lower.
At the 15 minute mark the attempt of the project is now to "project the sun and the moon onto a view plane" at a distance close to the observer.
"Viewing Plane" theory from the paper:
The construct by this author of
the paper in question just shows that she was unable to explain the event in any other way.
She is basically using the inexplicable "celestial sphere" idea where bodies are projected on a celestial sphere like a planetarium and straight lines become curved, which is also described in her work as appearing in astronomical literature.
Current thoughts: Her work seems to be mathematical fantasy to try and explain something that is not able to be explained.
I will continue watching when I get a chance.
