I don't think that necessarily contradicts what the author is saying. Even you describe how these top 10% performers are often underpaid, so in some areas (getting noticed, managing office politics, switching companies to get pay rises) they seemingly "don't know what they're doing". A lot of people are brilliant in one particular area and at the same time fail basic life tasks, even though to someone from the outside it looks as if they've got everything figured out.
