Mission Completed?

[condorz38]

Just finished a dogfight 1 on 1 and got mission completed. The score was 1 to 1, but I still got a mission completed. I was killed first then I shot down the other player. Mission completed came up; scoreboard read kills 1 crashes 2 stars 1 for both players. I cannot understand this, as other games have been the same and I get the mission failed message. So my question is, does this mean in an even match does the player with the last kill get the win or is this just a one off mistake?
