Both myself and the vehicle owner fond you post very interesting. The concept of a transmissions life time bring 261K miles is valid.

Even if it had regular fluid changes every 30k and the transmission failed right now at 261k, that's good service and the transmission has now reached the end of its life. So since this trans is at end of life (living a good long time, as long as anyone can reasonably expect a transmission to last) and it never had a fluid change, the fluid did indeed last the life of the transmission. You can argue that it may have lasted even longer with fluid changes, but the truth is nobody will ever know for sure if it would have. Like I said, it could have just as easily failed at this mileage even with regular fluid changes.
