I think it's slightly different. Purity is less of a problem in the wild, as long as the outcome is an animal that can fill the same ecological niche. Saving a species shouldn't be an end in itself, it has to serve a purpose. I'm not saying that it could fill the same niche in this case, but with less than 10 individuals you'd be getting desperate and that solution seems more desperate than purely idiotic.
In captivity (and I don't mean conservation programs), keeping the lines pure serves no other purpose than satisfying the keepers.
