Then either the person who told you this is misinformed or they are talking about something different from the OneWorld Circle Pacific fare. The Star files for the CIrcle pacific fare are here:

from which you can see that rerouting is permitted at a charge of USD100, and the tickets are valid on any OneWorld airline.
