1) the actor in a live TV show is supposed to act out the rage and break stuff, but for some reason he thinks that he is not supposed/allowed to damage things. Correct.
2) off the camera the actor is told that breaking stuff is alright. Essentially, yes.
3) the actor starts breaking things correct and the audience is pleased with the show. No idea about whether the TV audience liked the show or not, but the cast and crew were relieved.
Is it correct? Mostly. Do we miss facts in point 1)? yes, what is the reason the actor thinks he should not be actually breaking the props at that time? Between 1) and 2)? no, it's essentially correct. In point 2)? other than what I pointed out, no. Between 2) and 3)? no In point 3)? other than what I pointed out, it is correct.
