What you describe - authorities used by people off your network to resolve A records with IP addresses outside your network - is not what Joe was describing. What the recursive name server your end users queried to resolve names, the IP address in their desktop's control panel, outside your network?
I can see a small ISP using its upstream's recursive name server. But to the rest of the world, most small ISPs look like a part of their upstream's network.
