Only the E-M1, and only for C-AF and legacy Four Thirds lenses.

Not quite. It uses it with native MFT lenses in S-AF too. We just don't know precisely for what purpose yet. See here:

Initial direction information, maybe?

Could be, and that would be smart of course. But the accidental observation of mine to which Timur refers is that if you do two consecutive AF-S operations on the same target with a sufficiently short time inbetween (and it must be very short), the camera will not go through a new CDAF cycle on the second trial. Everything will stay put and you'll just get a confirmation sign. If you wait a bit longer between trials, however, the second cycle would be carried out in the manner you'd normally expect. This leads me to suspect that the camera might be programmed to use PDAF (at least for the purpose of checking whether a new AF cycle is really needed) in burst-mode shooting, even when you use AF-S rather than AF-C, to keep the AF time down to a minimum in that scenario.
