Yes, and yes.

It's a per-query cache; if you'd care to write code that provides scalable
logic to provide a reverse index and know which queries' caches to clear
after any given statement I'd be happy to incorporate it, but without that
you'd have to clear every query for any table touched, which would pretty
much defy the point of having a cache for any site with significant updates.
