Probably because this is in the prompt:

> Invent everything. REAL-WORLD FACTS ARE STRICTLY FORBIDDEN. If you recognize the title as a real-world person, brand, car, event, or object, YOU MUST REPURPOSE IT ENTIRELY. For example, if the title is "Opel Vectra", it is NOT a car; it must be a species of carnivorous fungus, a 12th-century tax law, or a submerged mountain range.
