He didn't left both games.
But that has something with resetting scores. Because only one game count.
AP//EU//PRO PUB empty 1485 | -15 ( After score resetted there was 1500, loosing -15 ).
sdem eu noobs +1 PUB Demon Witch 1491 | -9 ( This one was played before score resetting, so it's ok ).
Games before resetting score are saved but they wont affect on score.
That's explanation.
