It sounds like he's using a standard 2X anamorphic cine lens on the camera, which means that he will have to crop in post on the sides to get the image back to the standard 2.39 ratio.
If the sensor is capturing at 16x9 (1.78) then the unsqueezed image would be 3.56 : 1 if left uncropped -- and if the sensor is capturing at 2:1, then he would get a 4:1 image when unsqueezed.
So wasting the sides of the captured image in post is necessary to return the width back to a standard 2.39 ratio for release. With a 2X image squeeze, you only need an approx. 1.19 : 1 pixel ratio on the original to get a 2.39 : 1 image.
