I just tested it in my studio this afternoon with a view camera. Focused on a wall and marked the location of a picture on the wall with a grease pencil on the GG. Moved the back laterally 10mm. Lo and behold, the picture was now exactly 10mm from the grease pencil outline. This is the same no matter what lens I put on the camera. Sorry, but you're wrong.
Try it again, only this time ROTATE the camera (or "pivot" if you prefer) and tell me if the focal length of the lens doesn't make a difference in how fast the image sweeps off of your ground glass.
