It was just a joke. You linked a thread about one particular camera artifact but missed the fact that there was another thread about this specific case. I've read all of those threads.

There's not really much ambiguity here regarding these factors now:

- it's a small bright infrared light source attached to a parachute

- the star shape is a camera artifact

The full quote is "don't cite the deep lore to me, I was there when it was written". The intention is to imply that he was there when the thread was created.
