I have never read it, but if it is designed for low stakes he would be telling you to play a hand like K4s under the assumption you can limp with a table full of other limpers. Drawing hands like flush draws and straights go up in value when people will call down to the river and their is not a lot of aggressive raising. If you table is not like this, ie people will raise strongly and will not call down to the river, then his strategy would not apply.
