But I'm even worried about the case where the *original* author does it.
So I developed a patch from a GPLv3 file.  I now go back and "develop" the
same patch from the GPLv2 file, which has all relevant parts identical.
The resulting patches are identical. Making the claim that these two
identical things done by the same person in the same way have different
copyright statuses might be legally correct, but as a practical matter
seems absurd since there's no way to tell them apart as they're identical.
This is a very bizarre situation!
