No it doesn't. They are Attribute Flags that allow multiple worlds to be used in them.

And to count ein or zwei or drei as DDW? That makes no sense unless you were planning to make those decks with nothing but DDW cards which I don't believe will be very good in a tournament setting. Just use DDW if that is what you want.
