I actually did forget the way it’s introduced, and went to check it again, it’s a pretty enjoyable book. I think though in some sense just seeing one example isn’t always enough to understand the moves and when they’re likely to work. Hence I still think you can probably just try to absorb the techniques quickly if you don’t have large amounts of time to stare at a diagram or set it up on a board 
I agree though that for instance one would probably have to put in a bit more work, imagining which are key stones making a tesuji work or not, numbers of liberties at play etc (I don’t see why these things couldn’t be pointed out though in a book )
I’ve been reading the SmartGo books version, which I find really convenient for testing out things
