Ah, I see, way as in path, not way as in direction (which is I think the misinterpretation that leads people to the root of the misunderstanding). So, there's one path to get from x -> y, but it does not imply you can't get back to the original x. In that respect, "way" is an unfortunate word to use, at least as it's used in modern English.
