I'd say that the King had more leeway to act upon the issue as part of his reform than his daughter will have when she ascends the throne in the future. If the King felt it important to continue the agnatic line of the House of Bernadotte he would have found a way to do so. Since he didn't I interpret it as him seeing his daughter as both the monarch and the future head of the house and not his son.
The Bernadottes in general have proven to be quite unsentimental when it comes to cutting off branches of the family tree either because of need, convenience or for misbehaving.
