FS, that's actually not true. You need to use two other than the program that you are getting the ticket from.
Just making some assumptions from your questions, it looks like you want to use your AAdvantage account to fly British and Cathay but not American. That is fine.
I am actually going to reconsider this advice and say to ask. The language is ambigious and AA has offered to do it in the past. There was one time that I had to use BA and CX exclusively (I never actually took the trip), but it was no problem with ticketing it. Anyway the wording is "Travel must include at least two oneworld partners other than American Airlines or American Eagle." It says you must fly on two partners but it does NOT say you *must* fly on AA. In any event, I would expect that it wouldn't be too difficult to just throw in a short segment somewhere to satisfy the condition. But I would personally just book the ticket and see if they say anything. If they do, worry about it then.
As far as a paid RTW is concerned, you can use any number you want, although I think the only way you could use only one carrier would be on BA since they codeshare to the US from Australia on Qantas.
