He's saying the truth of the conclusion is independent of the means used to demonstrate it. This is correct, but a rather confused observation. Since the question isnt whether the conclusions is true or not, but whether we are justified in believing it is true. And we are not justified. The experiment engineered its results; and no subsequent experiment has demonstrated the conclusion. So if it is true, we have not yet discovered that it is.
