I’m not an English expert, but I am a native speaker. Although the above sentence is understandable, when you look at it closer the sentence structure is a bit wonky. Anecdotally, I don’t like starting a sentence with “However,”, and this article has that twice. I think it is that kind of style where the author is making a statement and then forcing you to hold it in memory, so to speak, is what the commenter is referring to. It gets mentally taxing to keep track of all of the threads.
