The owner ID is informational. Affiliations are only relevant for the
purpose of scoping identifiers. The only place they show up operationally is
in an SPNameQualifier, at least that I can think of right now.
And no, you would basically never set those to be the same, it doesn't make
any sense. The affiliation is a group, the owner would be a specific entity.
