Not really, the sensor position doesn't have to be reset between the 4 exposures. Instead the maximum (individual) exposure would have to be divided by 4. So while doing a 20sec exposure, they would divide the 20s into four 5s exposures. Using an electronic shutter and pixelshift every 5 sec without resetting the position.
So it is possible, sort of, the result though would probably not be that great with the added problem of the distortion from (some) lenses causing the stars to make trails even if everything is perfectly set up. But then sometimes it could work just great.
But I don't think they have messed with the astro tracer software at all. Instead they have just added the PS part as a function separated from all the rest. Just a guess though.
