I didn't describe it good.
Silva was talking about the last fight they had, where it ended in a disqualification because of an upkick while Okami was still on the mat. He believes that Okami could have continued but chose just to get the DQ win. So Anderson feels like that was a KO for him.
For further clarification - Silva didn't say he had no interest in fighting Okami. He said he wasn't interested in a "revenge" fight (for his DQ loss). In spite of the loss on his record, he felt like Okami lost the fight (and I guess he's satisfied with that). In fact, Silva said that if Okami earned the right to fight for the title, he'd do it.
