Well, I was never taught that -- which is a good thing because it is
not true.

The most intuitive way to prove this (antenna tuner or not), is to
simply supply more and more power to the load. You will eventually
burn it up.

Now, had the VSWR been better (ie. a better network Return Loss), it
would have taken even more power to achieve the same "charcoal"
results. So VSWR matters.
