What happened in that match, CrusniK, was:
You played, everything was normal, then either one player left and took one with him or appeared a table with seconds increasing from 1 to 10 usually, and if two players were rejected, they both dropped. Those players were you and some other, so you both saw everyone else leaving/conceding, but in reality it was you dropping. The left players probably finished the match or the losing one conceded.
