It’s not contradictory but could be worded better.

From the LLQ draft:

   The client begins by sending a standard DNS query for the name of the
   LLQ, with type SOA. The server MUST answer with that SOA record in
   the Answer section, if the record exists. The server SHOULD include
   an SOA record for that name's zone in the Authority section, if the
   LLQ name (type SOA) does not exist. For example, a query for
   _ftp._tcp.apple.com. may return an SOA record named apple.com. in the
   Authority section if there is no SOA record named
   _ftp._tcp.apple.com. If, in this case, the server does not include
   the SOA record in the Authority section, the client strips the
   leading label from the name and tries again, repeating until an
   answer is received.

We can make this more clear.

Fixed.
