For me, it may be that the toilet paper roll needs to have the open end away from the wall. I don’t want to reach under the roll to take a piece! That’s ludicrous!

But it’s a design for designs - it tells you how to design your own UIs, it doesn’t dictate what for example a calculator app should look like. You can follow Material Design and still end up with a terrible UI design.
Surely that’s enough for some distinction, right?
