Yes, methods are cached. Changing @ISA causes the cache to be invalidated except (apparently) for non-inherited methods. undefing or redefining the subroutine rather than the whole package is correctly handled by the caching code. I'm not surprised that the caching code doesn't expect people to undef the whole package. (:
