It would be rather helpful if you sourced your quotes. The Queen's Bench ruling (which does contain the apposite phrase in para 71) in
http://news.bbc.co.uk/1/shared/bsp/hi/pdfs/02_11_11_assange....Except that if you'd read further (or not taken the Wikileaks edited highlights) the court immediately goes on to say "Nonethless, as the material was put before us de bene esse, we will express our view on what difference it would have made if we have taken it into account in determining whether the description of the conduct was fair and accurate."
The court did specifically look at whether the offences alleged would constitute crimes in the UK for instance in para 96:
"In our view, therefore, the description was fair and accurate; the offence was, for the reasons we have given an offence under the law of England and Wales; the requirement of dual criminality was satisfied".
On the rape question in para 109: "In our view on this basis what was described in the EAW was rape." it even goes on "A requirement of proof of coercion, if that is what Swedish law requires, is a more onerous test for the prosecution to satisfy than the test for consent in the 2003 Act".
So the court went "you showed us this, we don't need it but we're going to point out how it doesn't help your case anyway". Assange got spanked by the British Courts, repeatedly, who were convinced that he had to go to Sweden to assist in the investigation into serious offences. Despite the best efforts of some very experienced and serious lawyers no Human Rights angle was found to stop it either.
