Considering the car in question it might not be so much highly processed luncheon meat as it sounds. The filter faces forward with the dome leaning up. There's plenty of room for dirt to accumulate on the block atop the filter while driving. This does happen. Maybe there was enough there that unscrewing the filter allowed some dirt to "fall in" as such and the oil could have trapped some dirt on the mating surface.
