Continuity mistake: The first prisoner is moved up to the Holo Court and has his memories searched for incriminating evidence. Once they find the memory of him refusing to pay the temple, it shows the hand of the 790 Unit operating the machine pressing a button, and next to his hand is a switch that is in the down position. Once the Holo Judge passes sentence on the man, it cuts back to this spot again, but now the switch is in the up position with the 790 reaching out to flip it down, which causes the rail to switch over and put the prisoner on the track to get his organs cut out.
