Ferrari SF-26

Can anyone think of a reason why it might be beneficial to shed counter-rotating vortices onto a driver’s face?

Counter-rotating vortices cancel each other resulting so no vortex. But also help to settle turbulence coming from the interface of the halo and tub. Or the two vortices split and run either side of the helmet and thus tidy up the flow generally.

The video below is B-Sport's interpretation of why Mercedes can get away with putting the little "4th-elements" on the top corner edges of their rear-wing. He thinks it's a glitch or error in the legality-box rules that allows a team to put a mirrored aero surface a few centimeters long pretty much wherever they want on the car. I wonder if this is what Ferrari are using to allow these halo winglets; they appear to be a similar size.

Ferrari have the rotating wing too but only declaring the halo winglet

I thought they just use the 2 cm freedom for the HALO. Is it larger?
