I believe [MENTION=794258]Leaping_Deere[/MENTION] was talking about nesting another ticket within the RTW and wanted to keep everything in one PNR. If the other ticket is on AA flights, BA would not be able to issue it on its plate in a BA-created PNR unless one is using the oneworld Visit North America fare.
