Seems to imply it. Conversly, if you go to the “all possible worlds exist” level of a multiverse, then each novel (or other work of fiction) in our world describes events that actually happen in some other world. If you limit yourself to just the “there’s an infinite amount of stuff in our world” multiverse, then only novels describing events that would be physically and otherwise possible describe real events.
