I don't think so, when I saw it happening, without the slow-mo I knew he was going to go. He is a head taller than the guy and he was all around him bringing him off-balance. I can see why you are calling it sanitised but for me personally, I'd happily go even harder for shirt pulling. I think, the important part is to make sure that the same behaviour gets treated the same in every match - thats where there isn't a good job done, but it is correct to penalize such things. Casemiros opponent was obviously faster than him and would have been away without that.
