To be fair, they might have made that sound like a new special deal they'd made up just for him, but that's standard UK policy. We don't have the death penalty, and so we won't extradite anyone to a country where they are likely to get the death penalty.
Nothing stopping them from either extraditing him to Sweden or Australia where they might be more willing, or asking the US to pinky swear that the worst he'll get is life imprisonment, which is all it would take to get past the "no death penalty" requirement.
Either way he's still got to serve six months in HMP for bail jumping before he goes anywhere else.
