Doing this you can overwrite changes done by local sysadmin.
Think about this scenario:
1. user installs jwhois
2. he does not like suids/sgids, so he adds an override:
dpkg-statoverride --update --force --add root jwhois 0755 /usr/bin/jwhoi
After this /usr/bin/jwhois is mode 0755.
3. some time later he installs new version of jwhois and unless chown
fails, /usr/bin/whois will get mode 02755!
