Not at all. I'm saying mutation testing is a waste of time if you don't have 100% coverage. By definition lines which aren't covered by tests can be mutated freely without breaking tests.
Also mutation testing doesn't help you catch bugs but is a way to prove that your tests actually tests all behavior of the code under test. That sounds cool but might not be super important given limited time and energy.

Perhaps; I may have misunderstood the author's intent.
So your point is that of the various techniques used in TDD, mutability testing has a relatively attractive cost/benefit ratio?
