Does it only ever send you to a party already in progress? I've done so about 5 times today, and it's always just that.
It would make sense if DF gave preference to placing you into a party that was already in the dungeon over a group that was in the process of forming. After all, DF can only fill those holes in parties already in dungeons with people who have that option set when searching.
Your experience is probably an indication that there are more parties in dungeons that need to replace a member than there are people willing to join a dungeon run in progress. If there were more people with that option set than there was a need for, then you would start to see cases where you get placed into a group that is preparing to enter the dungeon.
