So instead of actually wearing a pumpkin helmet this shows everyone with one when they aren't actually one?
It shows other players that you have a pumpkin helmet on when you only have a normal helmet on. This applies to wearing any helmet at all. The player that has the "pumpkin helmet" on must have the required permission so that others can see it.
You do see your own helmet, it does not hide that. It just shows your helmet as a pumpkin to other players. You need to have a helmet on for it to activate it (along with the permission node).
