Both this and the Fourth-Wall Observer articles are getting the fourth wall metaphor wrong. For this one it's only in the title though. In a theater set, there are three walls that represent a room indoors. Therefore the "fourth wall" is the other one that isn't there, separating the characters from the audience. Breaking it means getting out of the stage, to interact with the audience. To put it in television terms, the fourth wall isn't the TV screen or the camera, but the very absence of a camera (or rather, the air standing in the place where the camera should be). So most characters DO notice and observe the fourth wall, it's those who don't that break it.
