The symmetry is broken by the direction of the inlet. Point the inlet the other way, the vortex will form in the other direction. Even if you started the vortex the wrong way, the incoming stream would stop and reverse it in short order.

Coriolis Force is meaningless on this length scale.

Still, that doesn’t mean it has to be an ad, it could just be run of the mill arrogance, or the writer drank the Kool Aid. It is funny though, like someone worried about the influence of the cosmological constant on their own body or something.
