You do still have state, but with a MPA you have a cleaner break between each page and thus far less ability for state to persist and cause problems (though there are plenty of technologies to shoot yourself in the foot if you so desire).

This reduces the overall state of every page, but still gives you decent technology to work with the state of the page that you just cannot do away with.
