MyPresenter new VS self instantiate: MyPresenter

[LNUitTutor]

Section 2.3 said: "Do not call new to instantiate a presenter that is part of your UI. An alternative way to instantiate presenters is to use the message instantiate: with a presenter class as an argument." Greate! But in the 12.8 we saw

MailReaderPresenter >> initializePresenters
   content := EmailPresenter new.
   noContent := NoEmailPresenter new

and in the 12.9 again

MailClientPresenter >> initializePresenters
   account := MailAccountPresenter on: self model.
   reader := MailReaderPresenter new

Why? Is it a bug? Has it any hidden meaning? It has to be clarified!

Indeed, there is an inconsistency in the message to the reader. I will look into it.
