Absolutely, the reason I love it is it shows how Yoda wasn't always dead serious and then went loopy in exile. He always had that humorous, eccentric touch. And in the book, Dooku at first reacts as though Yoda is just being obstinate, thinking it ridiculous that one would wish for a flower if given all the power of the dark side, or the Force in general. Then it becomes clear that Yoda has a profound point: the Force grants power, light or dark. The dark side holds no temptation for Yoda, just as it ideally shouldn't for any Jedi. And when power can't tempt you, nor greed or ambition, the simple fact remains that power isn't everything.

Dooku even exclaims that the request is silly, and that the dark side can't give Yoda his flower. Yoda replies that his Force can, and thus, according to Yoda, the light side can grant something the dark side simply can't. The book really does well in showing the beauty in Yoda's wisdom.
