No, he is right. This is what makes the combination of Obis so logically nebulous. If you are in Temenos on darksday with double light weather wearing Anrin Obi, you take -10% light damage from Citadel Buster instead of up to +25%. If you were wearing a combined obi, what should happen? They would have to come out with both an enhancing and reducing combined Obi to be thorough.
