Yes. They are file-ID-based.

True, although FSSpecs should have tracked the parent directory should it have
been moved or renamed. I'm not sure they did, though.
Also, remember that, unlike FSSpecs, FSRefs can only refer to existing
files/directories -- precisely because they are file-ID-based.
It's hardly surprising that the replacement differs from the original,
otherwise why replace the original?
