IIRC, XXX in comment is used to flag something that is bogus but works.
When the sentence introduced here in f5ab0a14, the fix for "DELETE ... USING" is not as good as it is now.(I guess
that'swhy the comment was added). And for now, IMHO, we can remove the comment directly.  

If my understanding here is wrong, please let me know and that would be great to learn more about PG.
