"org:" field in person object

In person object template, there is an "org:" field:

martint at T60:~> whois --version
Version 4.7.5.

Report bugs to <md+whois at linux.it>.
martint at T60:~> whois -h whois.ripe.net -t person | grep org
org:            [optional]   [multiple]   [inverse key]
martint at T60:~>

As I understand, this is for organization object(?). In which case
this is needed? So far I have never seen a person object with "org:"
specified..
