They were actually supposed to win this game in Pistole Round 2 after switching sides, but what they didn't expect to see was Asuna miss what was practically a stationary target.

I still don't understand why he jumped in so carelessly in just a few moments.

1vs4 on Round 16 What a play?

There's nothing more than them not having to win, it's like they're destined. Many times when they're leading, they'll change their play for something, even though it's not necessary.
