My understanding of what Panurge said is that magical formulae often get their power from or through the cosmology of the culture in which they operate. Myths are often set before or outside of time, and often describe enormous changes in the universe (no fire > fire; big egg > universe; clumsy giant > rock formation, etc.). So if the incantation or charm references that period, it obtains some of that transformative power by sympathetic magic.
For example, if I have a disease and want to charm it away, I might refer to a myth about the way the gods subdued the demons, or a particular instance of a healing in my mythology.
As to whether that works, in the abstract sense, for believers: I would say “no” (or more generously, “unproven”). Believing in magic doesn’t make it real anymore than believing you can fly obviates the need for airplanes. But that is because I believe reality exists independent of our perception of it. That belief isn’t universal, either, and I’m sure someone will be along to call me irrational and illogical for clinging to it!

To go back to your earlier post, I have in fact a large shelf of books on magic, amulets, the occult, and similar beliefs from throughout history. And that’s in addition to a 23-volume encyclopedia called Man, Myths, and Magic. I even write (and, yes, publish professionally) fantasy fiction about magic and magical beings. I’ll match my historic, cultural, and anthropological understanding of magic against yours any day.
And that’s why I say that the how of magic is almost entirely neglected in historical records. The few possibilities that one can dig out are recourse to larger voices than humans. Sometimes magic calls upon gods (or demons or other supernatural creatures) to do work for humans. Occasionally, magicians can call upon natural forces (personifications of wind, fire, water) to work. Some sympathetic magic works by calling on similarities to work in similar ways.
However, except for saying that somebody else does the work, there is never a how in any body of work on magic. That is because magic comes out of a pre-rational state in which the “how” of ordinary processes is not known. If wind and fire are not understood than no theory of how to work magic with wind or fire can possibly exist. If no theory of medicine exists then sympathetic magic to make people ill or cure them cannot have an equivalent how.
It simply cannot be stressed enough that historical magic depended on a lack of understanding of how the world worked. It seemed perfected obvious to them that larger forces than humanity buffeted them invisibly. Disease, weather, aging, the sun and moon, everything in their world beat down upon people inexorably and without explanation other than recourse to god figures. Magicians were originally those who claimed to be able to call upon or manipulate or supplicate the god figures. All magic stems from this. In the west, with Christianity, the supplication of the Christian God became an official heresy, so other god figures were substituted, or, more safely, the manipulatation of natural forces in some arcane way. Non western cultures had similar developmental paths, but the details vary in a thousand ways.
All magic is similar in its underlying aspect, however. There is no “how.” The supernatural did things that humans could not, by means that no human could comprehend. That is why the rise of science, the age of reason, the enlightenment hit magic such fierce body blows. The substitution of workable - and reliable - theories of how the world operated obviated the need for supernatural intercession to a greater and greater extent.
Asking “how” magic was thought to work is looking at the question in the wrong way. It is an artifact of our current scientific age, in which how is not only a legitimate question, but the expected and necessary question. This did not used to be true. Nobody asked “how” magic worked. One might ask “why” magic worked. Today “why” and “how” are inextricably linked, but in a pre-rational society those were separate questions.
People thought magic worked because it harnessed the powers of magical beings. It’s as circular as that.
