That is a pretty logical argument. The Swedes have a legal system that is going to be quite different from the Anglophone common law systems and we can't really predict exactly what will happen. As monocasa linked, the Swedish legal system is not in a position to resist US demands backed by a threatening attitude. One incident is more than enough to establish that Sweden will likely fold if pressured.
It is reasonable to think that the Swedes have identified a different avenue that they can use to have Assange leave the country care of the US, and that they would exercise that option once they have him in custody.
That is almost certainly what Assange thinks. I don't know I've ever seen the likely penalty for what he was charged with, but I doubt it is more than a decade and he would have spent longer than that in the Ecuadorian Embassy the way things were shaping up. His actions are only rational if he is expecting the US to be involved.
