Is this weird? 4 speed car has auto linkage

This is a bit of a head scratcher....perhaps I am going senile. While inspecting my new 4 speed '70 Swinger project and wondering what I have to remove to drop the engine and suspension out the bottom I see what appears to be column shift auto linkage in addition to the 4 speed z bar. Its connected to the column but nothing on the other end (obviously....it has a 4 speed in it). The column looks like a floor shift column at the top but not at the bottom as it has linkage. The build sheet say its a 4 speed and it looks to have a factory hump. It looks like power steering was added as it did not come with it. If someone changed the column out for the power steering (is it shorter?) why would they install the auto linkage on the frame? Perhaps I am missing something?
