Still the same answer... as long as you only grind off one link from the stock chain, you would just need to use a new master link of the same size, type, and manufacturer in order to re-install that chain.
Aufitt's photo that you previously posted shows shortening a 120 link chain, down to 108 links... he was actually installing a non o-ring chain for race use on his bike. Unless you are doing the same (installing a non o-ring chain for racing), or are replacing your original stock chain because its worn out, there would be no reason to grind off a link from your chain, just to re-install it again.
