You mean like with Morihei Ueshiba and Sokaku Takeda?
If that's what happened, maybe. I don't know. But then again, O Sensei called his art Aikido, not Daito-Ryu Aikijutusu. Calling it "Aikido," he was doing his own thing; you can't criticize him for that because it was his. But if he'd continued to call it "Daito-Ryu Aikijutusu" even though he was doing things differently from Takeda, that would not have been good.
