Well that is how delegation works, sure there will be discrepancies as we have today with NS records and glues, but that is an operational error/problem we have to deal with. >> While I think using IP addresses for authoritative server selection >> is a natural choice there have been cases where an authoritative >> server on the same IP answers differently deepening on the domain >> asked, which will not work well with the detailed implementation of >> that draft. > > The point is that this draft is an opportunity to state clearly what > we expect from the authoritative name servers.

I mean that the same server on the same IP can answer (or not answer) when asked for a different domain. It (Unfortunately) is an observed pattern used by authorities when they are under attack.
