More generally, I think that this game is about jurisprudence in general, and interpretation of laws in particular. It’s not about mathematics or group theory. If it was framed as “in preparation for your PhD in statistics, you need to count 1 for each instance of ‘vehicle in the park’ group” I would count 1 for toy vehicle in the park. And for many more, too.

The way the game is framed as “interpretation of the law,” it includes the supposed intent of the law.
