The author is splitting hairs, creating their own definition of the term without reference. When hair splitting, backing it up can help make a point. To my knowledge there is no official definition of the term, so both cases the author describes can be considered "obscurity". Interestingly Wikipedia states that with Security by Obscurity the main mechanism of defense is obscurity. That definition is interesting and that with that definition "obscurity" is certainly bad.
