Actually, thinking about this some more, when
Lagging PF then the VArs are lagging the P. Therefore, your statement is correct, but your text appears to be using the convention I mentioned in the post above. The book is backwards and bizarre, it confused me too. Sorry, but
Lagging PF = Lagging Q = Positive Q.
Everything else I said above is correct. I never really think in terms of leading of lagging Q, but rather leading and lagging current and the consuming or supplying of VArs.
