I think there is a difference here between the game Phil's book is addressing and a low limit game.
You may be talking about higher limit games too, but I just wanted to point out that in low limit you can build a bigger pot by calling and letting in more players pre-flop (without risking as much). Raising in some low limit games could get pretty crazy as people will 3 bet with AK suited and others will still call with AQ, AJ, A10 (or even Ax suited, KQ, 72os, and 94 suited of course
). And 1 in 8 odds of hitting your set vs almost assurance you will see overcards with your pair of 4s, you don't want to get in a betting war with these hands IMO.
