By which he means: if Kiri wants to memorize herself like a book, she wants the opposite of the kind of self-knowledge that the prince has and is pleased about. If it were somehow possible to know himself so perfectly well that he could never again have a moment of realizing what he's going to do only after he has decided to do it - and he doubts it could be possible, however many sweela primes might try it - there would go much of the appeal of continuing to live. Surprise is one of his birth blessings for a reason.
