It doesn't.  3456 is a unique identity known to the home operator (i.e.,
anyisp).  NAS associates the user's session with 3456@anyisp.com; the
NAS can refer to the user's session by this identity in future for
example to resolve charging disputes.  The NAS also reports this
identity in accounting request.

The later one.
