As I do not have a copy of the printed book I cant verify it but, most likely the downloable version is not the final version. I know the team that reviewed the book and I'm quite sure they would not have missed such an obvious mistake, but having said that, with the pressure to get the book to the presses it might have slipped through.

As for the book being appetising.
I read a few chapters and I can tell you it is a fantastic book
I actually feel more strongly about typos. If there's a bunch of typos throughout a book I'm reading, I start wondering "if they didn't get these details right, what about the details of the other stuff?".
Copy editors, or whoever it is that catches all those little typos, are worth their weigth in gold, imho.
