Oleg, SOW engine abuse by pilot?

Maybe your plane has a different engine? What is meant for a Lycoming or Continental might not apply to a Wright or Pratt.

I have experience on small engines like the Lycoming and Continental and on P&W Wasp and RR Merlin, and the procedure is the same on all. The one you see in the training video is a military procedure, but the engine is considered switched off when the magnetos are off. If you move the propeller of a plane that has just stopped and the magnetos are on, it's very likely the engine might have some pistons firing. The choice of cleaning the explosion chambers depends also on the weather and temperature conditions.
Magneto switching is a very important part of the preflight checks, before take off you bring RPM well below idle and try running the engine on one magneto at a time, all you should get is a circa 100 RPM drop. If your engine quits with just one magneto off it means that the one that is on is faulty.
A dual magneto system is not meant to burn mixture better, it's a redundant system to have extra security.

Where did I state it otherwise? The subject was a dead generator during flight.

yes, dead generator means dead systems. Game over.

EVERY kind of battery, dry or fluid, loses capacity when the temperature drops.
And fluid batteries only freeze when they're flat. If charged, the freezing point is well below 0 C.

the batteries used on aeroplanes were meant to operate at low temperatures.

Anyway, would be strange don't you think? Starting the engine from battery, thus operating all systems, until the generator kicks in. Why do you assume that everything will stop if the generator dies? I wouldn't fly a plane that's so poorly engineered!

..then you don't want to fly in most WW2 planes or light sport aviation planes. If your generator fails your battery won't be able to run your systems for long. Most of the engine ancillaries like magnetoes and primary pumps (at least in WW2 planes and light aviation) are actually connected and powered by the engine by means of reduced gearings, but you will still need the generator to run other components (flaps, aux pumps, ligths, gunsight, some instruments, radio, some cooling systems etc..)

And the engine doesn't quit, because magneto's use their own power.
From the wiki: "Because it requires no battery or other source of energy, the magneto is a compact and reliable self-contained ignition system, which is why it remains in use in many general aviation applications."

does wiki mention the fact that some systems that keep the engine running and performing adequately need electricity? You mentioned the FW190 kommandgerat which I think it's the perfect example.
