It’s possible he is.
However, the rings of Saturn are without doubt in my mind a late creation of the catastrophe that destroyed the Saturnian system. One reason I think so is that ice, which makes up the rings, doesn’t last long in a vacuum as it sublimates directly to a gas under low temperatures and, especially low pressure. You can’t get a much lower pressure than the vacuum around Saturn’s rings. You can actually see examples of sublimation in your own home refrigerator’s freezer section in the ice tray as the ice slowly disappears if you don’t use it right away. Over months, and years, the ice cubes shrink with sublimation even though the temperatures don’t rise above freezing.
I think the crescent is the reflection of the on coming Sol, stealing the electrical power from Saturn, and the appearance movement of the crescent (the celestial boat) around the orb of Saturn is proof of this. There could not have yet been a shadow on the rings from Sol, until after Sol had captured Earth and Saturn was receding and the rings had formed from the remnants of the atmospheric plasma cloud that had surrounded the system. His logic to explain that portion of the Egyptian crown is exceedingly good, but is explicable only AFTER Sol has entered the picture as Saturn is receding to its now distant position.
This is the image I'm talking about which is the claim which David Talbott and the Thunderbolts group make about the Saturn crescent which you see in iconography:
The claim is that matches what you see in iconography, particularly Shamesh glyphs from around the ancient near East, e.g.
One of the problems I have with that is that it looks to me at least like you'd have to have some other large body, possibly Neptune behind the Earth i.e. between Earth and the sun to cast a shadow like that on the face of Saturn.
Note that even at a fairly late date, the Southern / Saturnian system had smaller bodies up fairly close as orbiting bodies and then the larger bodies, Venus, Mars, and Earth back further away in an electromagnetic alignment leftover from the original Herbig/Haro string configuration.
The reason for the roughly 26-degree axis tilts of Neptune, Saturn, Mars, and Earth, presumably, is that when the Southern system was captured, those bodies, still in an inline arrangement, flew into the plane of the sun/Jupiter system from the South at a rough 26-degree angle and, as those bodies peeled out and began to orbit the sun as they do now, ordinary gyroscopic force caused them to retain that angle of approach in the form of axis tilts.
