The gap is measured from the straight edge inboard to the rim of the alternator pulley. The thickness of the alternator pulley, like you said, is greater so this difference has to be added to the 3mm. This is because my pulley is inboard from the plane of the crank and waterpump pulleys. The difference can be seen just by sighting along the centers of the pulleys.
5mm difference is half of the belt width and will probably work but I agree this doesn't seem right at all. The factory must have messed up maybe? Or maybe VW wants extra friction on the waterpump pulley?
