BIND 9.x definitely does do negative caching.  I'm just not certain
offhand how one determines whether that's going on, for any particular
query.  I hadn't really thought about that, before.

It's a pretty good guess, though.  I'm sorry I don't know how to
determine if it's correct.  (I'd appreciate hearing any answer you get,
really.)
