That's the deal.
Also, if your entire sight moves, you may wish to place your shortest distance pin high in the window so you'll have plenty of room below it for additional pins. I leave just enough room on top of the pin for a deer's height at 20 yards so I can keep his whole body visible in the window, but leave my pin off of him until ready to shoot. It comes in handy when you have to draw when the deer is momentarily out of sight behind a tree.
