I would think if they really weren't using it at all he wanted to "put the "misconceptions they were to rest" he would just flat out "we're not using that right now at all" just like he has with the keyword meta tag, but he doesn't say it's not being used anywhere in the video.
I think Matt often gives what a politician might call a "nuanced statement". That is, he notices the SEO community going overboard on some idea and he trued to pull that back. Because of the complexity of the current machine learning algorithm, he often cannot honestly give a categorical denial. But he and Amit Singhal were extremely honest right after Penguin was released telling us that it was extremely unlikely we could reverse engineer the thing.
That's still the case, I think, and I'm wiling to back off on using this particular patent in my day-to-day thinking - even if some "anecdotal evidence" seems to pop up from time to time.
