Honestly I don't see an analogy on odas answer. He simply reffered to both instances at once. You simply believe that Odens attack was not with CoC so you could use an analogy as your argument and apply it to oda. Its more simple than that. He simply confirmed both attacks to be with CoC without any rhetorical stylistic devices like you think. Its even absurd to think that he would use this as an answer for the kid who most likely doesn't even get what a analogy or general rhetorical stylistic devices are.
I gave you an analogy with 2 cars, where i comment in the same way Oda did, but refering to only 1 of the cars. Same thing could apply to Oda's answer. But you, for bias reasons, think it is not the case without being able to proof that.
Oda's answer is not a confirmation since there are 2 possible interpretations of his answer.
