They should be more careful and specify that they are
talking about electrical lengths, not physical lengths.

They also should point out that, although a radiator physically/electrically
shorter than needed for first self-resonance can be "loaded" to resonance,
this does not mean that loaded and self-resonant radiators perform equally
well in an installed system. In some applications there can be as much as a
100:1 difference in their radiated powers, for a given power at the
transmitter output connector.
