Yes, but as far as I’m aware, pixel shift uses the same general control mechanism, just as horizon correction does. I could be wrong, but I thought that pixel shift was implemented in software, perhaps with hardware that evolved with finer tolerances in the later camera bodies.

I just wondered how Pentax got away with Pixel Shift when there are so many existing patents for the technique none of which seem to be by Pentax.

Yes, I understand where you’re coming from. I referred to the earlier Pentax patents more for their explanation of the mechanism, which I thought was what the OP was talking about.
