These are not EMD:s, they're Generic Domains (or in case of NFT.com an Abbreviated Domain).
An EMD is something like buyqualitygems.com, rentacaralicante.com, bestloans.net, etc. that's to say SLD's composed of phrases people search for when they're looking for a product or service. And while people might search for "chocolate," chocolate.com is not generally considered an EMD, because it's a single dictionary word, which covered under the class of Generic Domains.
Here, Mueller specifically refers to keyword-rich domains (e.g. domains with many keywords in them), and when you consider that, what he says makes perfect sense. Because if you own rentacaralicante.com for a car rental service in Alicante, aside from looking cluttered (like a spam site domain), if you want expand to other cities, say Valencia and Ibiza, then you might have to re-brand in some capacity.
I made this point in an other thread, but as Google's leading Search Engine Coordinator he can be held legally accountable for lying about how Google's Search Engine works, similar to how a Lawyer, Physician, or Economist can be held legally held accountable for giving you misleading advice in their respective fields of expertise.
