Agreed. I can understand NYC's reluctance to mention the obvious, but going into any building within the 20 to 25 km kill zone of a thermonuclear bomb seems to be pitiless advice. In addition to the fallout, there is a going to be a firestorm of anything remaining after the initial blast wave, and so, it is going to be impossible for anyone who survives the detonation to remain inside any structure for very long anyways.
The subways or sewers is where people need to go, if they wish to live.
Aside from anything else, the shock wave will follow the path of least resistance and flow along the surface of the ground. Any penetration will only occur under the blast itself, and even so the overcharge will remain largely atmospheric because earth is thicker than air, and energy seeks the easiest outlet.
Penetrator warheads are a thing, but they're not wasted on cities, they're spent on first-strike silos or underground C³I facilities.
