Arm anthropometry (and flexibility) can make a huge difference in how people can grip the bar. As noted in the blue book we want the chest up, elbows pointed forward and the bar resting on the deltoids. For some people this will have the hand unable to grip the bar (and just their fingers on the bar). For others, this may enable them to still have a full grip on the bar. So the bar may look to be in the hands or not in the hands depending on the individual. But what everyone should be trying to avoid is a rack position where the elbows are down and **the weight of the bar** is on the arms and wrists instead of the shoulders. In the video you linked the bar is resting racked on the shoulders, but you could argue that his elbows are not up enough so more load than we would like is being transferred to the wrists and forearms.
