The point of the article was that above around 120 or so (and also at the low tail), the tests become very unreliable (due to a chicken-and-egg problem of finding people to calibrate the tests on). So an IQ score of 160 is highly suspect, and subject to even 2-digit variance.

Aren't we supposed to calibrate the tests on (random selection of) the entire population?

In theory yes, but when the number of people at the tail ends of intelligence are vanishingly small, how does one check that the questions in the test can actually measure their intelligence accurately?
