That it is. Shorted coil around magnet partly closes high frequency components on itself.
This process goes with evolution of heat,energy conservation has not canceled.

WTF?

All logic is in getting better sound.

There is no shorted coil around the magnet, it's just a poise of copper foil on the top. Plus, if there was, it's in the wrong direction. If they wanted to use that approach to dull the tone, they would put a shorted turn around the coil, not the magnet.

This is just a poor attempt at grounding the magnet.

I thought shorted coil of foil was around the magnet. If it was that way then then foil around magnet would ve impair the performance at high frequencies of magnet itself.
In any case shorted coil would give more effect around coil more then around magnet. In "coil" case we can see the effect on spectrogram, in "magnet" case we need complex measuring station to see this effect.
And if it was an attempt to ground ceramic magnet, then it is even impossible to coment

To understand how the heating effect works in closed loop around the core with alternating electromagnetic field you can conduct a simple experiment:

1) You will need tube amplifier and AWG18 wire. Use the wire to make a shorted coil around power transformer coil.
2) Change standard fuses with pieces of nails for greater reliability.
3) Apply power to the amplifier

After this experiment you can boldly go to sound tests.

1) Make the same experiment as above with output transformer.
2) MASTER LEVEL 10
3) Fanatically play

Warning: Before conducting these experiments you must have carbon dioxide fire extinguisher nearby.
Also you ll get most accurate experiment results if youll use the most expensive AMP you can buy.

It is not a closed loop, and a closed loop in that direction around the magnet will not impair the high frequencies of the coil. It's perpendicular to the coil.

A closed loop around the coil will impair the high frequencies.

Exactly!

I think they had intended on grounding the blades, which they should be doing, but failed because the magnet is not conductive. If that pickup was built in the Gibson factory, they should be assumed of themselves. Although it's on par with that ridiculous SG bass pickup I posted.
