A natural thought here is that this last result does not distinguish between those participants who flip, win, and then rate the morality of their action, versus those who flip, lose, change the task assignment to favor themselves, and then rate the morality of their action. It could be that the former group (rightly) rates the morality of their action highly, since they are following the fair procedure, whereas the second group rates it low, perhaps around 4.0 as do those who do not even bother flipping the coin and just assign themselves the positive task. If the results came out this way, then we would have evidence for moral weakness of will, to be sure, but not for moral hypocrisy, since the second group would be honest about the moral failure of their action.
