The purpose of having multiple DNS servers for a zone is reliability
through redundancy. You should strive to have as few common points of
failure between the. If you have them on the same machine, there's not
a single bit of redundancy, except maybe the NICs if you don't use
virtual IPs. That's not very wise.
