When it looks up ns1.mymansions.com it notices that it resolves to the
IP address of the host it's running on.

You apparently don't know what "zone" means in DNS; a zone is a portion
of the DNS hierarchy that's managed as a single collection on a common
set of servers.
Anyway, the way that servers discover that ns1.mymansions.com is the
server that hosts those domains is via delegation records. The .com
server contains a record that looks like:
mymansions.com. IN NS ns1.mymansions.com.
and the .biz server contains:
mymansions.biz. IN NS ns1.mymansions.com.
and so on.
