You're totally right. I think the article is just inherently too reductionist, which is like of a foundation of analysis in general, is to reduce and then reason about some process/object. However, I think a lot of analysis is (for lack of a better term) critically reductionist, and they see that as a virtue of their analysis, they toss out nuance and details in favor of studying the "structure" of some process without considering that particular nuance or detail changes the structures meaning and possibly the structure itself.
