We must not get distracted from the important
criteria, that with the scale of observation being 430 light years as 13
kilometers, and the two axels being within a point less than 0.5mm such must be
allowed to be considered as two spins around the same centre with different
axes. That 2AU and R must be allowed as equivalent.

They are equivalent in regard to the mechanics involved in forming a star trail, but not otherwise, since they are inclined at almost 23.5 degrees to one another. If they were not inclined then, yes, we should not expect to see a different view to what we do see.
