It's a bug in the website's preview mode — if you look at the full essay, it has (if I've counted correctly) 25 paragraphs. There are also three paragraphs that start with "BC" for some reason, which seem to be bigger breaks.
There should be 7 paragraphs in the preview shown, with paragraph breaks after ‘reigns.”’, ‘on Amazon.’, ‘Well, yes.’ and so on.
I don't quite see why the author shuns them.
