Is says "based on", not that the user name is actually in the string.
(And it uses the uid instead, but same same.)

I thought I remembered it being a part of the scoring section of the
manual, so either it's been removed or I misremember.
But that's the reason the algo is the way it is now -- it allows you do
do stuff based on <ID.*@big-domain.com> in References/In-reply-to etc.
If there's only one UID per domain (which is the case these days),
that's less of a thing, of course.
