I figured I might have to explain this, but I couldn't figure out how to do it in the story.
I was thinking it was more or less gloating. He saw Pike and Shenshen as a Cutter/Leetah, even if it really wasn't. Kind of a leftover grudge that he saw. "He must be first in all things, or he is nothing." He didn't have much left to be first in, and even though he was humbled, he still went for whatever he had. I'm not going to say Pike thought it made much sense either. He thinks it's stupid... but it's not over yet.
