Of course it does not matter.
I believe the context of his comment was that if AY plated a RTW ticket, they would know the revenue and thus credit to AY+ accordingly regardless of marketing carrier. Therefore, he recommended that people should not plate on AY (which is kind of moot given the usual AA / CX / QR / QF that most people end up with).
