His point is that you are looking to disguise your range and make it easier to get people to stack off, not to limit the number of players to the flop. I actually disagree, as these types of players tend not to be observant enough for us to have have to disguise our range and are often willing to get stacks with meh hands in limped pots, so I find always raising unnecessary. Still, he's not talking about trying to limit the number of players who see a flop.
Playing these types of games isn't easy, but it is simple. Make a hand and get payed ridiculous amounts of fat value. All you have to do is bet for fat value, and very rarely for any other reason.
