I don't in this tactic because I feel like the author would have specified if it's necessary. I've used it in my own tactics sparingly to shut down specific players and disrupt their passing primarily, it can be very effective. Try it out! Almost always just the press more often instructions or show onto foot where I want the player to go would make a difference. But I don't overuse it for the entire team because I feel like it loses effectiveness. Would be curious to see what @knapthinks about that.
