Umm, this is a specification. It is *supposed* to be interpreted

But that is just an interpretation. There's nothing in the spec which
forces that interpretation.
fsync forces the data to disk. There may be one or more pathnames
which the application also relies on, and if the application does care
about those, the application will have to ensure that they are synced
too.
Look, I agree that your interpretation is useful. It's just not an
unambiguous requirement of the spec.
