Doesn't seem like the best tweet to die on to make your point. The results surely answer all of your questions.
It's a weird format, but I encourage you to at least try and appreciate it instead of dismissing it. I'll try: It's kind of like what a blog post might look when annotated on genius.com: each point can spawn its own discussion and people can engage the author on any subtopic right there alongside the content.
Another benefit of the anti-narrative format is that it has an immediate quickstart. One second you're reading the opening tweet about how "bullshit our brains are", and the next you've learned something interesting. You might not have even clicked into a longer-form format about how the eyes work, there's just no commitment.
