It's the same in Germany, but I still wouldn't expect the police to ask for my ID when asking for directions. The fact that you need to be able to identify yourself when asked doesn't mean that they are supposed to ask for it for every interaction.
I always thought as well that there is “Ausweispflicht” (ID carrying obligatory) in Germany.
I figured it worked the same in the Netherlands, but from what I can tell it's true that you always need to carry it and you can get fined if you don't. So quite a bit more strict. That sucks.
