I searched the archives looking for that discussion and couldn't find it;
can you provide a link?

That's appropriate when you're committing functionally identical patches
into multiple branches at about the same time.  In a situation like this,
though, I'd argue that the later commits ought to explicitly reference
the older one ("this is a back-patch of commit NNNNNNN").  As it stands,
it's very hard for anyone looking at the commit logs to make the
connection.
