I can’t speak from experience, but there is no reason for PDAF to work only in continuous mode. It is primarily being used in conjunction with CDAF to predict movement and to provide “depth”. The former should improve tracking albeit still limited by the fact that it has to rely on CDAF for full focus (as opposed to the hybrid focus system in A99 where this is carried out between OS-PDAF and conventional PDAF). Further tuning of focus is via depth information. In other words, OS-PDAF is meant to work under tracking conditions, or otherwise, but its effectiveness will largely depend on how it can work with CDAF. Consequently, the focusing speed improvement will be subtle and perhaps more easily visible in videos with less hunting and smoother focusing.

What i understood from the NEX-6 manual :

continuous mode use both PDAF+CDAF to get the best focus result.. but this can produce slower shooting rate

speed priority use only PDAF, and no CDAF ajustement. This provide 10 fps shooting rate, but with a risk of AF failure at each shot... on 10 shots, you'll maybe get only 5 with good focus... or more.. or less...

"Réglage continu de la mise au point et de
l’exposition pendant la prise de vue en rafale avec
priorité à la vitesse
Réglez [Mode autofocus] sur [AF continu] (page 83).
Réglez [AEL avec obturateur] sur [OFF] (page 129).
• Si la Détection de phase AF ne fonctionne pas, l’appareil photo cesse de régler la mise au
point même si vous réglez [Mode autofocus] sur [AF continu].
• L’exposition pour la première image est réglée lorsque vous enfoncez le déclencheur à
mi-course. L’appareil photo continue d’ajuster l’exposition pour les images restantes."
