Upon further reflection, I realize there's two "impedance matching". I, and other EEs, will assume I mean the complex conjugate matching to redirect power toward load.
The author is making the argument about minimizing reflections across a medium. The trumpet, and AR coating land. The other points are more tortured. The transformer example in particular invites nitpicking.
