I think there's more to that. Your interesting choice of words "he was caught" and attempted to "weasel his way out" seems rather deliberate to paint Damian as being dishonest or had something to hide. I invite you to explain how that is the case.
Maybe that was a bit harsh on my part. But I do think he gave an evasive answer. The question was very straightforward and to the point: "If we only needed a 2MP image, for instance, we would traditionally take a full resolution shot, and then downsample it with Photoshop. Does PureView provide downsampling algorithms superior to those of Photoshop or other image editing software?" His answer was very roundabout. Did he answer "yes" or "no"? My interpretation is that he tried to make the best of a difficult situation by effectively answering "no" in a way that still paints the PureView resampling in as positive a light as possible.
Good interviews often involve difficult and uncomfortable questions. It's the interviewer's job to cut through the hype and try to get a straight answer on things like this. A good interview brings new information to light instead of just rehashing what interested parties already know. Anyway, aside from being wrong about JPEG, I think Damian answered skillfully here, considering his position.
What I mean about JPEG... He said "But you're then handling the JPG file that was saved, so you're probably better off doing it at point of capture." But the question was framed in the context of the process the end user would go through to get the best possible image at a particular size. If you resample down from a full-res JPEG in Photoshop, you then have access to a clean, effectively unartifacted resampled image. But if you let the phone do the resampling, your resampled image now has the JPEG artifacts. Since the phone won't let you save a resampled image in uncompressed form, you have to choose the lesser of two evils. Which one does more damage to the final image? Using a JPEG-compressed image as input to the resampling, or saving the output as JPEG? I think it's pretty clear which way yields better results.
