Clan War Automatic Win

In the patch there was announced that in clan wars, once a team reaches the needed rounds to win, the game will end.

Improved Clan Matches!

Clan Matches will now end immediately when one team has enough wins to be declared the winner.

Is that not working (yet)? Or don't I understand how it works?

We played a CW just now, won both halfs and the score was 11-7. But at neither of those "wins" the game ended.. It was just like normal, the full 18 rounds.
