Once you are ready to push back, you would delete the fallback line and create a front line, as Germany now occupies Belgium/Luxembourg, and begin to push back. You would create a fallback line from Luxembourg to the sea across Belgium at first because once Belgium joins the Allies your front lines will become broken and you want to stand on the newly constructed forts that would have been created with the Extend the Maginot focus.
