The opponent didn't want to give up the battle either, because it was a bet between two people, and the stakes were high enough to cover a month's living expenses. So, the opponent played extremely cautiously in that round. Finally, he found a flaw and, after a combo, knocked out the person who should have won, then followed up with another combo to finish him off.
At this stage, the person who should have won was mentally unbalanced. In fact, if he had played normally, even if he was the first to lose, his mindset wouldn't have fluctuated so dramatically. But he happened to lose when he found the opponent's flaw, and his combo went wrong during the attack, which was not entirely his own mistake, but an issue with the machine or joystick. This is unfair for a competitive player, which is why his mentality completely collapsed during that battle. In his emotional upheaval, he became reckless as if he was venting, and his joystick operation was violent.
