I don't quite agree. A more precise title would have been: "We Disentangled our E2E Tests" If I understand correctly - what seemed to have happened is that they separated the lower level data-coupling testing and their higher level testing with contracts and acceptance testing respectively. Each of those layers don't need to know of each other, so this was a separation of concerns AKA simplification.
