Now I know.

It all depends on the rear tire arch. If the arch extends forward enough, it will prevent the window from rolling all the way down. Many of todays cars have "stretched" wheelbases, meaning the tires are placed closer to the ends of the car than they used to be. This allows the rear window to go down.
