If I were in charge of the air force, and Putin ordered large-scale air superiority attacks against Ukrainians, I wouldn't want to do that. Putin might not have the power to order his air force to launch strikes of aggression.
Dictatorships give the impression of being all-powerful, but dictators need to keep constituents appeased, but that's kind of an illusion. Key constituencies -- quite often the generals -- need to remain appeased.
I expect if this were the case, Russia wouldn't advertise this externally. There is every incentive to maintain a united external front.
