I’m not certain that I understand what you want to do. But if you’re trying to print the back overlay on the front of the next sheet of paper, I don’t believe that will work.
What you can do is use page definitions and form definitions to change the overlay which prints on a given page. Data in the printout, such as the text “Page 2″, can trigger the change to a different overlay. I would recommend an AFP tool to do this — something like Infoprint Designer makes it a lot easier to keep it all straight.
