A lot of people watch TV with a second screen device in hand.
But there’s no logical path that says they are using that device solely to interact with whatever is on the screen. Chances are high that if they’ve whipped out the iPhone, they are checking email, looking at a friend’s Facebook photos, checking the score of the game they’re not watching or some other activity completely unrelated to the what’s on TV.
