Sorry fellas its bullshit. Spetnaz do not train Systema they train Sambo like everyone else in the Russian military. Like Aikido, Systema requires compliant and cooperative partners. Without live sparring at 100% its theoretical. It’s easy to elicit a cooperative response from training partners when you beat the shit out of them when they aren’t fighting back. This is a common trend among traditional martial arts & Dilliman/ki touch type training that doesn't have live sparring. They practice conditioned response by beating the hell out of their complaint partner. This concept is similar Pavlov's salivating dog, over time the instructor’s partners become conditioned and are reacting based on previous experiences.
