Short Circuit
This isn’t just a matter of poor taste, it sounds like a safety matter. Electricity has rules, even if we don’t fully understand them all, and they should be learned and followed to the letter. Otherwise, someone might get elecrecuted or even worse.
Whoever designed this particular circuit probably missed a lot of classes at school, or was the kind of person who got their classmate to do their homework for them. I may not know much, but I know that someone accidentally switching off the light should not risk innocent bystanders getting caught on an elevator between floors.
