Nah. Sweden doesn't seem to have given any firm commitments about security beyond "We work on it together", which can mean exactly as little or as much it fancies Sweden after they are in NATO.

To me this is simply "Erdogan has decided he has seen this bargaining to completion and it would look really bad, if this thing wasn't resolved by Vilnius. Pressure started to mount with This is starting to be embarrassing Recep from rest of NATO" and he simply called it good.

Nothing needs to have been changed on this exact moment, He just decided he has tried long enough and has exhausted the concessions and no point dragging it on. Instead of benefit, it started to be more hindrance in his calculation to keep this going.

He can now tan in the limelight in Vilnius as the leader who saved the situation at last minute. Mind you the problem was of his own creation, but hey those are the best kind of problems. You have exact control and can "solve the problem" at exactly the most suitable last minute moment. Actual problems are harder for "last minute saviour" credibility collection. You might actually fail to solve the problem and thats not good.
