Yes, this does seem to be the required behavior, though it is unfortunate. For safety's sake, I suppose a UAC should never have more than one NOTIFY outstanding to a particular subscriber at a time. IMHO, it seems that there should be a special 4xx code for out of order requests, and that a subscription need not be removed if a NOTIFY receives it.
