Newbie to this site, please be gentle and guide me if I'm doing it wrong.

On this puzzle, I got really stuck, and I think maybe there's a gap in the solution given.

(SPOILER ALERT)

In the solution (p. 67) it says, "If he [the prince with the 125-ft beard] were Prince Kenneth, the one with the 100-ft beard would be in Goatee Castle (clue 1)..."
I don't understand why this is necessarily true. So far as I've gotten in the puzzle, if Kenneth were the 125-ft beard, according to clue 1, he could still be EITHER the prince rescued by Princess Shirley, OR the one whose beard was 25 feet longer than the prince in Goatee Castle.

Can anyone explain why the quote in the solution has to be true?

Thanks
