I think he meant it's a step in the right direction towards solving the technical problem of identifying who leaked the material. More generally he could have meant that tracking the leak is a step in the right direction towards HBO having control over when their material is released. Even in a fantasy world where all entertainment is free I think artists should have control over releasing their own work. In any case, I'm curious as to what the endgame is in the right direction you mentioned.
