No, it doesn't.

I don't think, this really is the reason.  Technically, there is no
way to update a zip archive (call it zip or jar or war or whatever),
you always have to create a new one mixing content.

Using the approach Jon showed in his first mail (move the old archive,
create a new one, delete the old one) is the only thing one can do -
that doesn't mean that Ant couldn't hide this mechanism from the user,
moving and deleting archives under the covers.
