I think it is because of the principle of it. Honestly even if I could wipe the floor with someone, something like that is so dishonest I would have done the same. At some point it is a personal decision, but it makes a bigger point to laugh at the H3H3 guy for being so pathetic he did such a thing than to just wipe the floor with his "representative champion".

Not that I would hold it against him if he did debate the other guy, but it simply makes a stronger point in the debate. Plus, from a strategic point of view, your opponent just virtually conceded you an easy victory, why not just take the victory that humiliates him vs a debate which will at best be twisted to you only doing ok [even if you did great].
