The question was, can they resolve to different domains.
The answer is, they can resolve to different IP addresses or
they can resolve to forward to different domains, or they
can even resolve to two different virtual or real machines
in a domain and forward them off to someplace else as in
a parked domain. Ping, trace, or route may return different
information, but whois will always map to the same information.

I think this is covered under RFC 1035, implementers are free to violate
any DNS conventions on their own system as long as all standard conventions
are observed from other hosts.
