I actually agree with your first sentence. At a minimum, it doesn't seem sustainable over any significant period without something giving.

That said, there are reasonable places that are in-between living very near the office or commuting for two hours. Given that the link is mostly focused on the monetary aspect, let's think about it. For people who do not work from home, he is basically saying that 1.) the constraint probably can't be satisfied for a two income couple; 2.) if you own a home you will probably have to sell it every time you switch jobs--which doesn't seem very economically sound; and/or 3.) you will have to be very selective about switching jobs.

I actually did have an extremely short commute for a long time but it went up to an IMO still reasonably sensible 25 minutes when I bought a house. I've kept the house through several job changes. The commute veered into the somewhat unreasonable range for a year or so but it's otherwise been well under an hour with an increasing amount of WFH and travel mixed in.
