Did you look at the output of dig?  It has

     flags: qr rd ra;

Note the absence of "aa" (Authoritative Answer).  This signifies that
the answer came from your local DNS cache.  The DNS server did not make
any external queries.  So this is not a valid example of an external
query that succeeded.
