I have been playing with this, and have concluded that motion correction is a software/firmware implementation that basically just scans the 4 images that comprise a PS image, and does not merge areas that show evidence of movement.
The K3II lacks the firmware to do this, so no motion-corrected JPGs straight from the camera but PDU5 will motion-correct K3II RAW files.
The Adobe pixelshift conversions don't (yet) correct for motion effects. The latest DCU5 does a far better conversion..

So I thought, does this mean that the K-3II has always had motion correction in pixel shift mode as per the new K-1, but it only needed DCU5 to catch up with the release of the K-1, in order to be able to display it? If so then this would make yet another strong case for using DCU5 for pixel shift development. Here's what I found, with an example that I took in April using the 20-40 Limited. These pictures are 100% crops of the same pixel shift DNG in DCU v5.5.1, the new version released along with the K-1. All I did was turn motion correction off in DCU5 and then back on again and take screen captures of both. The output is clear - the new version of DCU5 does apply motion correction to K-3II files! This pretty much makes the K-3II's pixel shift mode as good as the K-1's. So just when software like Lightroom and ACR were beginning to implement basic pixel shift algorithms, DCU has gone one better.
Motion correction turned on in DCU5:
