I was trusting the reader to comprehend that a conjugate match implies system-wide resonance - guess I should have been more explicit.

In a lossless system, a conjugate match *indeed* equates to system-wide resonance. Even if the system is only low-loss, the 50 ohm Z0 match at the tuner input creates a system-wide resonance. Prove it for yourself by taking your grid-dip meter and coupling to different points in the system. From end to end, you will observe the resonance dip.

Like you, some other people misunderstood the point of the article so I revised it and posted the latest revision on my web page.
