Am I understand correctly?
Not sure if OP has the same thing as mine.

A reversed image is back to front. e.g top left reversed would be top right. A shift from top left to bottom right is likely upside down. If you rotate the image (or your head) the view will be right way around.
Note the orientation of the head with respect to the telescope, horizon and object position all cause rotation of the image.
A straight through finder will show an upside down image but not a reversed one. For reversal you need an odd number of reflective surfaces.
A reversed image cannot be matched up with a star chart whereas an upside down image can.
