Look at the 'Fred' gate example I gave. It is constructed using two Nand gates.

If you were to then use a 'Fred' gate in a subsequent design, that design would still qualify as using only Nand gates because the 'Fred' gate is built using only Nand gates. The use of the 'Fred' gate is merely to manage the complexity and control the degree of abstraction -- something which is an explicit goal of the authors.
