Confirmation is a term from SAML which is honestly not well understood
by many people (myself included) but I'm trying to be consistent with
that in how I use it here. But it's not necessary and #5 is just
stating how the <SubjectConfirmation> element needs to look. Perhaps
rewording it to just not use the confirm language would be better?

No, it's just language around what needs to be validated in the
<SubjectConfirmation> element of the assertion because it is a bearer
assertion.
