Basically there's no need to always be betting or raising when you have a very good hand or the nuts. Specially when you know villain will do your betting and raising for you.
The worst thing you can actually do against some villains is bet or raise as it'll just scare them away(make them fold) when you have a very good hand or the nuts.
Phil Helmuth has a similar quote in one of his very first books from way back when.
