Look inside the exhaust pipe
You think they are generating a vortex?
Seems to have a clear twist there doesn't it. I've noted before about (I know there's very defined rules on this exit) that it appears very tight and without any "flare" at all right at the edge rim periphery.
Thought before that it may focus on further projection of exhaust energy (along the lines of a jet thrust aperture modulation for full takeoff thrust) to "pull" the rear wing departing flow more effectively into detachment.
