 Okay, here's the setup. We've got a trolley coming down the track and then there's John Stuart Mill holding the lever. If he does nothing, then that trolley will go down the right side of the track and go along its merry way. If he pulls the lever, then the trolley goes down the left side of the track. So here's the question, will John Stuart Mill pull the lever? In this case, it doesn't really matter whether he pulls the lever or not. There's no other real information so presumably the consequences are the same other than maybe perhaps the train going to a different destination. But the consequences are the same, it doesn't matter whether he pulls the lever or not. Okay, now we have a different setup. We have the trolley on the track and on the left side there's some poor person laying there. They're not moving, you can't yell at them to wake them up, you can't go over there and pick them up and move them out of the way. Yet the trolley is moving down the track and John Stuart Mill is waiting with the lever. If he doesn't pull the lever, then the trolley goes down the right side leaving that poor guy on heart. If he does pull the lever, well... The question is, will he pull the lever?
