If I knew how that worked I would have invented it before Subaru did
If I were to guess however they could sense wheel speeds and/or use sensors (gyros, accelerometers, etc.) to see the loss of traction coming and adjust accordingly. It's not that far fetched.
When it snows here, it snows fairly uniformly. The whole road is covered in snow. If we're both sitting at a stoplight, I have all 4 tires' traction right away. Your car doesn't know there is snow on the ground. Mine doesn't need to know. Your car waits for input from wheel speed and throttle position sensors and reacts to that input, but there is no input until you start moving.
