I get the idea. Android Market is essentially Google's iTunes now, and they want to push the music/movies aspect. Google Play makes more sense than iTunes branding does (tunes are about 1/8 of what it does these days), but there is some weirdness. Play works well for music/movies/games, but not really for apps/books. I was introduced to the brand with an update to Google Books app saying it was now Google Play Books, which made me think Google was expanding into sports team management or something.
