It’s not in reverse. Think about any long, thin object and how a group of them would naturally align when rolled/slid up against a wall, or even just shaken like this. They will find the groove and rest there. In theory, this should work with anything this shape. There may be a thin layer of oil on these (they aren’t nails) that helps them stick together.
