I took it to mean that you did not have to do anything for either the Germans or the Allies. The industrial point shift and the repair were already considered. It would seem odd to say that it has already been built in if you need to subtract it from the Allies, roll for repair, and than add it to the Germans. What is more confusing is what happens if the Germans decided not to invade Belgium on one of the alternate plans?
Then Belgium keeps trading with Germany and so supports the German war machine?
