Yeah, I laughed when I read that sentence. Although some rules in law have naming conventions that tell you something about the underlying rule (for example, the merger doctrine, or assault with a deadly weapon), a huge number of rules are named after the case that created the rule--or, in other words, just a person or company's name. So in administrative law, you might apply Chevron deference, or say that a post-hoc rationalization poses a Chenery problem. And, of course, sometimes lawyers disagree about what case created or recognized a rule, so you'll have some people calling something Auer deference, with others calling it Seminole Rock deference.
