This is a good observation, because this tactic is a hallmark of Putin and authoritarianism in general. What he does just lie about something where he knows it's a lie and the audience knows it's a lie, and he knows that the audience knows that he's lying, but the audience is powerless to correct him, so it is his way of demonstrating his power over the audience. He is saying to them that he is so powerful and dominating that he is in charge of their reality.

Masha Gessen has written a fair bit about this.
