A big difference between this and that is that this appears to determine relative positioning through multiple mouse-style optical sensors, rather than visually checking relative to patterned tape.

With a Raspi-cam and some Apriltags or some other fiducial markers, the visual reference could also be possible perhaps.

How does it solve linearity and repeatability problems of mouse sensors? Or is it just not mouse like but not in literal sense?

Yeah IMO the Compass appears to be a more convenient design

The reason Origin uses tape is to maintain precise, absolute registration over large distances - so that you can for example machine a pattern the size of a kitchen table.

I am very skeptical you can have that level of registration with mouse-style sensors that can only measure relative motion. I might be wrong, but it seems unlikely.
