What I gather is that they can judge a distance from the shooting distance information, focal length and lens profile and the PD information. From that, within limits, they can reconstruct what is hidden in blurry areas with deconvolution.
A less sophisticated but kinda easy to understand example of deconvolution:

With the phase difference data at hand, Canon can shift the focal plane. The normal DLO in DPP does not have that phase difference data to work with, and it only reconstructs unsharpness form the lens, AA-filter, and other aberrations. This advanced version is pretty neat?
