The interviewer asks about her credence ‘right now’ (at an awakening). If we want to set up a betting problem based around that decision, why would it involve placing bets on possibly two different days?
If, at an awakening, Beauty really believes that it’s tails with credence 0.67, then she would gladly take a single bet of win $1 if tails and lose $1.50 if heads. If she wouldn’t take that bet, why should we believe that her credence for heads at an awakening is 1/3?
