The examples shown in the post aren't wrong because they fail the grep test, they are wrong because they A) capture an uninteresting abstraction that is not likely to see much usage as the program gets more complex My understanding is the point of doing the grep test is to avoid capturing uninteresting abstractions not likely to see much usage as the program gets more complex. If you are a programmer who sometimes loses sight of the program's real goal because you're worrying about code duplication, the grep test might be useful for you.
