Later on in [] he says that the measured particle becomes entangled with the apparatus, as the whole system evolves according to the many body version of his equation, and that the only [fundamental] discontinuity is a mental one as the experimenter takes note of the result of the experiment.  He explains quantum entanglement quite clearly and thoroughly, but seem not to have an answer to the EPR paradox.  There is some real philosophy of science there, addressing issues that I have not seen covered in Wikipedia.
