Neat. Firstly, that isn't high bar. Not low bar either. More "middle bar". Secondly, I, and pretty much everyone else here, do not wear a squat suit, therefore modifying the bar position to take advantage of the suit holds little relevance. Thirdly, there are world records that were set with low bar.
I think the biggest thing to take away from this is that Dmitry is a very strong man.
