Well yes but it goes deeper than that. If you'll notice, most of the other legendaries clash with one another. Usually they have types that have advantages over one another or that represent their elemental clashes. However, Ho-oh and Lugia have never been portrayed as enemies. They're some of the few legendaries out there that don't fight with one another in the lore of the games. Therefore, their types wouldn't inherently clash with one another because they are not meant to be enemies.
