I don't think those were ghost faces -- I think that was art from the Skorp enemy. At some point in the loop, the game loads art for the capsule, and since only so much art can be in memory at once, the capsule's art goes over that of Skorp since there isn't a Skorp nearby. By missing the trigger point for the art load, the game aligned the tiles in the correct order to draw the capsule, but didn't actually have the capsule art ready and drew what it had in the position that art should have occupied.
Oh, and dubbing videos is lame. :(
