Toilet signs

I saw this today in a cubicle at our local station. I'm wondering why they felt the need to explain how to flush so many times.

This was next to the above. It's something I'm not sure is found in any other country: a recording of water flowing to cover up the sound of you doing your business. Apparently Japanese women are a bit shy about this. It's a water-saving device, some women apparently tend to flush prematurely to cover up their bodily noises.
