Yeah. Alvarez is a badass, but that was intentional. He has been drilling in that position for hundreds of hours. You do not even need to see the guy to know he is a downed opponent, you can feel it. If you wrestle, you can probably relate. You know your opponents position just as well as your own. One could give him the benefit of the doubt for the first two knees (the good ole' touch-the-floor-to-play-the-system game), but the third was outrageous.
That said, Eddie had been seriously hurt just minutes before. Maybe he did not have all his senses together. I hope it was this, cus, like I said, he is a warrior and a martial artist.
