For sure there are cases (plenty of them) where the second principle continues to hold (entropy goes up). I was just pointing out that there are very natural example where that principle breaks down at cosmic scales. Such an example is exactly how our planetary system was born.

People know vaguely that in a few billion years our Sun will collapse and it will either become a supernova or become a star where the fusion reaction is a higher one (instead of hydrogen+hydrogen->hellium, something like hellium+hellium->carbon). At some point possibly after trillions of years, all the nuclear reaction converge to produce only iron, and from that point on there's no more fusion and fission, and later on the heat death of the universe occurs. Well, even if there are no more nuclear reactions, the universe will not die from reaching a maximum state of entropy (heat death), but may continue to evolve forever, going periodically through states of higher and lower entropy.
