I've noticed that this kind of formulation of a prediction is defective for the purpose of calibration on things like predictionbook. If, instead the prediction was "Amanda Knox will be lose the appeals process AND Amanda Knox will be extradited", to complement your other question then the predictions continue to mean what predictionbook intends them to mean and if people answer both predictions then they have also provident the conditional prediction information.
