My German is a little rusty, but I'm almost certain that this is a recommendation from Das Umweltbundesamt (national environment agency) against using hot tap water for food preparation:

https://www.umweltbundesamt.de/themen/trinkwasser-das-beste-lebensmittel

Auch wenn die Mengen gering sind, sollten Sie für die Zubereitung von Lebensmitteln stets frisches Wasser aus dem Kaltwasserhahn verwenden.

The middle paragraph, translated to English:

Drinking warm water from the hot water pipe is only recommended to a limited extent. Because it has stayed in the pipes for longer due to the circulation in the hot water system. Circulation is necessary so that everything comes out of the tap hot enough to avoid legionella formation. On the other hand, depending on the cable material, substances can come loose. Even if the quantities are small, you should always use fresh water from the cold tap when preparing food.

So yes, you're right. It's not recommended to do.

Hmm, interesting.
I live in a place where hot water is either from a continuous flow heater, so basically no extra circulation; or from a small under-sink water heater where the water is kept at safe temperature and the distance to the tap is near zero.

But I guess in places with these big, central hot water storage thingies what the article says makes sense.
