Of course it 'covers' it, as you said. But I suspect you would agree that the whole point of the saying is to comment on people who beat their head against the wall doing the same thing over and over again, fail at it, and then continue doing the same thing without any recongnition of the facts. No one comments on someone who does the same thing over and over again when it succeeds.
