If that nameserver still thinks it is authoritative for that domain, then
it will continue to respond to queries for that domain with the
information that it has, which is almost certianly the old site.

Put another way, if my DNS server thinks it's authoritative for, say,
yahoo.com (for whatever reason) then anyone using that DNS server to
resolve hostnames will get whatever my server thinks is valid for anything
under yahoo.com.

The ISP needs to remove the domain that it is no longer authoritative for
from its servers.
