To a small extent on very bright objects yes it can happen.
I beleive the reason for this happening is a reflection from ones eyeball back onto the eye lens (terminology?) of the eyepiece. It appears to be a function of brightness of object viewed, the quality of eyepiece lens coatings, and a large eye lens on the eyepiece.
Cheap ep's with inferior coatings will suffer this to a much greater degree.
As for the Saxon vs GS dob observations, yes the saxon paintwork is far superior. Standard sticky tape holding a bit of paper to my ota being removed resulted in paint comming off with it

The friction control on the Saxon is far better than the springs on the GS.

A scope will always be at its best when balanced. If you can get your scope balance point to be at the altitude hubs, discussions of the pros and cons of springs vs tension handles is probably moot.
I would be very interested to know if anyone critically compared the optical quality of the Saxon vs GS dobs.
