Well if a server answers non-authoritatively for a zone it is
suppose to be authoritative for, it will be logged as a lame
server, and then the caching DNS servers may flag this server as
BAD, and not bother querying it again if some one asks another
question about that zone.
I think this is what is causing the problem. No idea if being
lame also affects the credibility of the results, and other
subtle aspects of how responses are handled, so it is possible
other DNS caching servers might come to a different conclusion.
DNS administrators don't have to be perfect, they just have to
create perfect DNS data.
