This paragraph confuses me.  If I'm writing, for example, a file manager
and I want it to update its display automatically when another task alters
the contents of a directory, I don't care whether the modification was
done locally or remotely.

If I understand the SMB protocol correctly, it allows the client to take
out a lease on a directory and not send its modifications back to the
server until the client chooses to (or the server breaks the lease).
So you wouldn't get any remote notifications because the client hasn't
told the server.
