I think you mean section 4.3.2.
I looked at it, and I couldn't find a way how it could produce two NS
RRsets in the authority section. But I interpret "If a match would
take us out of the authoritative data, we have a referral." narrowly,
that is, this happens only if the server is not authoritative for the
QNAME under consideration. A zone cut is not sufficient in my book.
