That's probably a fair assessment. I don't really read books like this for the code precision (heck even sample repos on github don't survive working over much time). I look more at the high-level gist of concepts, so for that it's good, and then I know what to Google next... I wouldn't even be surprised if the book is totally out of date in a few months.
