In the simplistic example it could be argued that they have equal power. In a real scenario they likely don't. In a real scenario, the dark slices may or may not be irrelevant; Bob must also consider making a deal with Charlie, who was left out of the example and has 6 dark slices of his own, or with David, who has 3 dark slices. There is also the pizzeria across the street to consider which gives Alice and Bob each 3 dark slices.
