You're right, they're not geographically right on top of each other.

But, in OSM we have these "relation" data primitives to tie different
thing together.  In this case, we use relations to tie addresses and
roads together.  I think this is in case of things like the road getting
moved.  The address nodes at least don't become orphans.
