It's assuming you'll still experience the perception of having a choice. It predicts your actions but doesn't tell you, how would that be different from choices you're making if you actually did have free will (in both cases you say "I think I have free will" whether or not you do)? Since you have imperfect information about yourself (this neuron talked to this neuron by these rules) you don't attribute the cause of your own behavior to anything other than "I did that". I think the example from 1.3 is much more clarifying than the one-box vs two-box problem, there's no "predictor" involved
