If this were as thoroughly studied as we were led to believe, then we would already have known about this effect. And yet we're just not learning about it, which leads us to wonder...what else are we yet to learn about it?

If you dig into the actual data cited in the paper, the assertion that recovery was demonstrated at T3 is dodgy at best. The study authors may have put some reassuring language in their commentary to get past political roadblocks to publication. I would not have added the quotes myself, but they're not necessarily misplaced.
