I sent queries from 270+ different locations for the domains you mentioned off-list and I didn't see any inconsistencies. The persistent host-caching/browser-caching theories seem like your best bet (or my 270+ locations weren't sufficiently diverse to catch a stale zone being served by an anycast authority server).
