Drawet stop

I went to home depot and was advised to screw the drawer stop in like the picture on the left but your horrible diagram looks like u should screw it in like the right drawer stop( pics I have attached). I really need help to me a person who doesn't fix things your diagram is horrible. I understand you can't do a video, but how hard is it to take a great pic of the drawer stop installed on a real drawer and post it. The pic that you have on the diagram of the drawer stop all alone shows it facing down. So should I screw it down like that or up like the home depot guy said after he viewed your horrible diagram
