In this match,

why was Alexis Lebrun celebrating when he lost,
and why doesn't the game end when An Jae-hyun scored the first two sets?

In the competition format here matches don't matter, sets do. First team to 8 sets wins, so Lebrun was happy that he got a set for his team, even though I'm sure he's disappointed that he didn't win more.
