What's the difference between conceding in round 1 and round 2?

I didn't see any saves here – I'm sure there was no difference, but in theory, the opponent could have surrendered himself, disrupting your plans (@no mana/MP for DD/TP). Maybe you offended him with your attitude towards the game (and therefore, towards himself), who knows. Of course, he acted inappropriately, but appropriateness isn't written in the rules.
