It was spamming the thread. He could have explained it in laymen's terms and either provided links or post it on his homepage.
As it was, people got to the point of scanning the posts and as soon as they recognized the diagrams they'd seen dozens of times before, decided that there was nothing new to be found and didn't read it.
If there was something new buried in them there was no way of knowing without reading the WHOLE thing again, and people just don't have that kind of time. It would have been better to just post the new stuff so that people could have seen it, and link the old.
