The front facing cameras aren't for tracking the eyes.  They are for getting a 3D image of the room.

I was referring to the front facing cameras on the smartphones these headsets use.

Eyetracking cams usually work with an array of infra-red lights around the eyes and infra-red cams tracking the pupil movements (~250Hz seems to be the magic number to enable FovR). Smartphone (visible light) cams probably won't get enough light to reliably track the pupil, especially at 240+ images per sec. Btw I've yet to see a phone with cams at both ends of the display.
