The claim by him is that the land-based J-35(A?) has wings that are closer towards the rear of the aircraft, while the carrier-based J-35(B?) has wings that are closer to the front of the aircraft. He also alleged that the J-35 that we saw a couple days ago is indeed the land-based variant, i.e. J-35(A?), without pitot tube present.
It's easier to see the differences if you compare the gap between the vertical stabilizer and the wing. The gap is visible in one (AF version) and almost non-existent in the other (navy)
