If QNAME = foo.bar.example.com and NXDOMAIN SOA owner = example.com, you know that foo.bar.example.com and bar.example.com are not delegation points. You know that foo.bar.example.com does not exist. You do not know whether bar.example.com exists. (You can find that out with another query if you want to raise the NXDOMAIN bar.)
