The principles worth stealing
It lists the good ones — width and depth across the zones, positioning and body shape to receive facing forward, rotation to disorganize markers, creating numerical, positional, or dynamic superiority, fixing defenders to free space elsewhere, and only progressing when you actually have an advantage. That last one is the discipline most young teams lack. They force the ball forward because they think they are supposed to.
My honest take on 'playing out'
There is no single right way to play, and building out from the back is not automatically the right way for your team on a given day. If the opponent presses with numbers and there is grass in behind, the brave, correct decision might be to go long into that space. I want my players to build out because they read that it is on, not because a coach told them real teams do it. The principle is progress the ball with control. The method depends on what the game is giving you.
Coaching the judgment
So the thing I train is the read — do we have a superiority here or not? If yes, play through. If no, keep it, switch it, or accept the longer ball and win the second phase. That is a decision, and decisions are what I coach. A team that can only do one thing under pressure has not been developed, it has been programmed.
