This video contains a lot of useful information, and surely the info from a IPF champions are always interesting because you have the chance to understand how a champion think.
However I really don't understand how is possible to transfer the reaction force, given from pushing the shoulders against the bench, to the barbell.
The point of application is the point of the contact of the shoulders on the bench. Indeed the reaction force have the same point of application, that is not the barbell.
Anyone can explain better this section of the video?

Don't worry, you're not misunderstanding physics. ;) The normal force isn't going to contribute. I think someone showed him a force diagram when the bar was racked and when it is in the lifters hands and he misunderstood what he was looking at. The rigid arch helps of course though.
