Actually Corrik himself may have stated why he would choose youI wanted to see if he flustered. It was a bad choice all things considered. Ironically, I almost claimed it against wallz. Imagine how funny that would have went down. But, I decided I didn't really like blades comments on knightz towards the end.
So he could say "Blade would never claim power to counter a roleblock accusation."
Then again that could apply to many players
