One of Omon's "teachers" explains the idea behind the charade: even if the fact that the Soviet Union is a champion of peaceful space exploration holds true only inside a person's head (namely, the hero's; no one knows of him or his mission apart from its organizers), this is not any different from it being the reality. The reality, when it concerns subjects not capable of being experienced, is in fact only a perception formed in people's consciousness, and can be manipulated to the extent that the question of "true" version of events becomes meaningless.
