It's possible that you pressed a long note twice very fast at the start or repressed at the end of it. If this happens in the timing window of long note you can break combo without a miss, a 50 or even a 100.
However, this is not specific to multiplayer.
You pressed the LN very late (between 121.5ms and 155ms late), breaking your combo, but released at the right time. Because of the low OD, it counted as a 200 (Great) instead of a 50 like it would happen in most maps. You never get a miss if you release a LN at the right time (even if it is a LN you re-pressed).
