The Apparent reversal of solar wind is actually a second solar wind. This is a 2D simulation and wind that is moving away from point of view may actually show up as a reversal. The arrows on simulation indicate wind speed so reversals with long arrows could be very close to a reversal. Since solar wind cannot reverse the only conclusion one can draw is that we are seeing a second wind from a second star.
