I think you are confused. I don't play on PS so I may be wrong but if you click Invited Users under Microsoft Player Access it will still let only invited users into the world, Microsoft user or PlayStation Network user, it doesn't really matter. I think the real issue here is the fact that it says Microsoft Player Access when it should be referring to all players not just Microsoft Players. Again, I don't play on PlayStation so there is a good chance that I am wrong!
