something queer going on

And there's a hundred ways that there still could be limits and Gallifrey being an exception for some reason (Bad Wolf?), and so on and so on, but it was more important to Moffatt to show the upside, and it really undercut not only the Doctor's decision at the time, but his decisions since and in the future. Personally, I'm quite happy that Gallifrey isn't destroyed and that there was an alternative to genocide, but it was just so shallowly and clumsily done. And he shouldn't have scolded Kate Lethbridge-Stewart when he had made exactly the same choice on a much bigger scale and hadn't undone it yet! Kate Lethbridge-Stewart wasn't committing genocide, at least.
