Yes, that is what I am saying, he is describing effects of noise floor MODULATION.What? You're saying he's not talking about hearing when he says explicitly that: "one can hear levels of noise floor modulation down to -200dB". There's no other meaning to the word "hear" that I'm aware of.
if noise floor modulation is say around -120 dB (typical class D) you get considerable hardness and glare; at -140 dB its grain in the treble; below -160 dB then things sound much smoother with better instrument separation and focus. This continues until about -200dB (and perhaps even lower - reducing RF noise is not something that has an acceptable limit).
