You don't get strong concrete hints in games.
As far as I know, the idea of drilling these problems is to recognise shapes in certain local situations which you can turn to your advantage. The abstract hints in the book can serve as general questions you can ask yourself while playing: "Can I give White poor shape here", "Can I save those three stones" etc. But mostly it's about developing instinctual recognition of shape on the board so that you see the answer before you ask the question. It also has to do with giving you more ideas about candidate move selection, i.e. which moves to look at first when reading out a position in a game.
I imagine stronger players will do the book and not look at the hint and just the board to see what they instinctively recognise or not from shape.
I'd love to be corrected here, since I know I could be wrong and mostly write this post to see if I am wrong.
