It seems a little tongue in cheek to me. Sampling with no low-pass antialiasing filter in general seems like a different problem from sampling with no low-pass antialiasing filter where you _know_ that they only spectral content above the nyquist cutoff is gaussian noise. That said, his takedown of their approach makes sense to me. It's hard to really judge it though as my signal processing is getting _really_ rusty these days. I guess that's why we have professors. :)
