I think what it highlights is that the meaning of words depends on context and stripping all context from a rule and situation makes that ambiguous. Reading more into it than that seems silly.
Thank you! Language, specifically legalese, tries to make precise something that can't ever be. It's why "language prescriptivists" annoy me because it's not even a preference difference it's simply impossible, you can't define any word completely. Worse even if you could your definition is only good for a point in time.
Even simple things like chairs, you can't write down a definition that includes everything that humans consider chairs and excludes everything humans don't consider chairs.
