Yes, the form this article discusses is not what I would call a list.
To me, a list consists of bullet points, each of which is no more than 1 sentence. It's not prose as such. I'd also assume that the list might be hierarchically nested.
The article seems to be discussing listicles (or list articles): effectively a series of very short essays that parallel each other, making the same point from a different angle each time, or comparing and contrasting a series of subjects. It's a suitable form if that's the over-all point you're trying to make.
Mainly the article extolls the virtues of organising prose into relatively-short sections, each with a clear heading. I agree this makes prose more readable, but I don't think that's an uncommon opinion.
The article explains why lists aren’t just headings on top of paragraphs. For example, the list can be read in any order. There is no dependence between them.
