I think it was supposed to be that he was just causing them to happen to 'awaken' Wanda while he stayed out of them.I would have loved to see how they would have worked Dr. Strange into the commercials. However I get why they decided to keep him out until his movie.
But, it turned out that Wanda was already pretty woke when she left the hex to confront SWORD. Well, mostly woke, a lot of things was still hazy for her. And Agatha was interfering.
But the commercials were a lot like the 'in-show' opening and closing credits... they were generated subconsciously because she was in TV land. Except for the one time she called down the closing credits to tune out Vision's complaints.
