It's all in the article, the "offensive" communication examples you describe fall into author's definition of defensive communication categories, which he names "Control", "Strategy" etc.
The paper says about those, "Behavior which a listener perceives as possessing any of the characteristics listed in the left-hand column arouses defensiveness." So the author doesn't describe it as defensive behavior, and he's not even concerned with it as behavior, only as a perception that might arouse defensive behavior.
