Lol. Pretty standard to tell courts and investigators: "Hey, how about we meet at my place instead?" (on top of that at a place where the investigators don't have jurisdiction)
It actually is pretty standard. Sweden has done it in many other cases. As Wikileaks highlighted when this was made into an issue.
One thing that would complicate this matter is that there doesn't seem to be an agreement between Ecuador and Sweden regarding this. Given that JA was under Ecuadorian jurisdiction it's entirely possible that this was one of the reasons why the prosecutor didn't go down that route initially.
