nslookup

I made a DNS change a few hours ago and I just ran the following command with the following output:

nslookup mydomain.com ns1.mynameserver.com
Server:  ns1.mynameserver.com
Address:  111.111.111.111

Name:    mydomain.com
Addresses:  222.222.222.222
      333.333.333.333

222.222.222.222 is old IP. 333.333.333.333 is the new IP address. Why are they both showing up? Since I'm querying the authoritative DNS server directly, shouldn't only the new IP address be shown?
