That's just the thing, that's not the point of the prefix at all. The point is to denote a difference between stories which we have deemed invalid. Z:WBYJIE is still a valid story because they had the rights to use the Zygons, as discussed in a previous forum. We don't dabble in canon on this site anymore because it's a complex concept which isn't what we're looking to cover for many stories we discount.
