Yes, but currently, XBO games are NOT UWP games. XBO games and UWP versions of those games are separate code bases. What I'm saying is that at some point in the future, it's likely that all games on Xbox will be just UWP games and not the current dichotomy of XBO game and UWP game.

Thats fine and i dont disagree with it. But thats an argument for releasing more UWP games on the Windows store, not making them Play Anywhere titles.
