Yes.  That will work if *all* records in both domains should be identical.
But if he wants the same IP's for www.domain1.com and www.domain2.com, but
different IP's for mail.domain1.com and mail.domain2.com, they need their
own files.  So I posted the configuration that allows for the more general
solution.
