Of course. Everybody expected that, but Phil Spencer talked about it as if they weren't going to do that. That's the issue. He initially lied.
In the article I linked he does say that Xbox doesn't need to release the games on PS to be profitable (or make a ROI from the deal), but in the quote, he clearly states that his intention is not to block those games from other consoles (which he clearly did).
You put the quote out of context.
Simply put the entirety of what he said, stop interpreting things, and eventually you will understand the various cases are possible according to him.
"This deal was not done to take games away from another player base like that,"
"Nowhere in the documentation that we put together was: 'How do we keep other players from playing these games?' We want more people to be able to play games, not fewer people to be able to go play games."
"I don't have to go ship those games on any other platform other than the platforms that we support in order to kind of make the deal work for us. Whatever that means."
First and second part : the deal was not made to take away games. Meaning :
it was not the purpose of the deal, certainly doesn't mean that it can't happen still...
Obviously, they made the deal to make more money (that's what companies do... not to prevent people to play games). You can reach more people by not releasing on PS/Nintendo and releasing on smartphones through cloud, for example...
Third part is a simple fact : he doesn't have to ship these games on PS/Nintendo to turn a profit. Again, it doesn't mean that he won't do it.
Anyone finding confirmation that "he lied" or "he won't release games on PS/Nintendo" with these citations is making up stuff. There is not a single thing confirmed. If anything, he stated what the situation was. Any decisions he takes will be based on this.
