No his points were
Luffy and zoro fight kaido and zoro gets the last hit and kills him
Or luffy beats kaido and zoro kills a beaten kaido
He never addresses the actual point
Luffy beats kaido
Kaido gets up
Zoro kills kaido in dragon form above the Flower Capital
If Kaido gets up, then he won't really be defeated now will he.
In Luffy's first fight against Kaido, he give it his all and Kaido got up, same thing happened on the rooftop when he used Kong organ, Kaido got up. The scabbards give it their all and Kaido still got up, thats why you always bet on him, because he always gets up. For him to be defeated, it must be such that he cant get back up.
Defeat in one piece is when you're either dead or incapacitated. The only way possible is if Luffy defeats Kaido, and much later faces Zoro for another fight, which I doubt will happen.
