If it's a normal 400m athletics track (leisure=track + sport=athletics),
it would be reasonable to interpret the lanes=* tag on the context of
World Athletics rules.

We don't really need to deal with the contingency of tagging things
which seem unlikely to exist, like vertically stacked 2 lane athletics

I've never seen a circular swimming pool with lanes. Do you have a link
to imagery of one?
