Because RFC1996 says so. Please read it. I quote:

2. Definitions and Invariants

... 

   Notify Set      set of servers to be notified of changes to some
                   zone.  Default is all servers named in the NS RRset,
                   except for any server also named in the SOA MNAME.
                   Some implementations will permit the name server
                   administrator to override this set or add elements to
                   it (such as, for example, stealth servers).
