Not necessarily true. In some respects, PDAF does use contrast to detect focus. The difference is that there are multiple sensors accross the entire frame.

No, that is not the difference. You don't know what PDAF is or how it works. PDAF using a single focus point is vastly superior to CDAF at tracking moving subjects.
