I found his comment about Swedish prisons to be interesting. From what I've heard and read, Swedish prisons (and Scandinavian ones in general) are some of the most mild in the world.
I think he answers your question: "That's because in 47 percent of cases, prisoners in Sweden are held incommunicado."
I've read (in comments on blogs, so apply grain of salt) that the prosecutor in Sweden has requested that he be held in detention incommunicado, and that this is normal practice in Sweden for foreigners awaiting trial. And then the Swedes can slowly, slowly prepare for a trial and he can perhaps disappear for 1 year.
I believe you're just thinking about "Norway prisons" not "Scandinavian prisons". It's probably just Norway that has those prisons in some kind of natural reservations.
