Do we need a 'sync' to make sure no stale ephemeral nodes observed (created by exipred session)

we know that for some performance reasons, different clients may have
slightly different views of znodes, for example, if client A updated node
a, and it let client B to read the node a, client B might still read the
old data and it need a 'sync' to see the latest.

Do we need to do the same thing when we concern about reading some stale
ephemeral nodes which are created by some already expired session?

Thanks Regards,
