Yes, it uses the already-installed host's tools, because they're the
ones that match the running kernel. The new tools in /usr/obj may
invoke syscalls that don't exist in the running kernel, for example.
For the most part the tools used by installworld perform file system
operations (e.g., cat, cp, mv, chmod) and don't actually change file
contents. There are a few tools run at install time for which this
isn't true (like strip) though. That list of tools needs to be kept
small and carefully controlled to avoid introducing backwards
compatibility issues.
