A side view showing how the fences attach to each other with the jig (white plywood)... via those blue fence clamps on the left and with the blue micro-adjusters on the right.
Just unclamp the left ones and the right auto-detach because they use rare-earth magnets.

Once the fence is aligned and set to the desired spot, it locks down with those tall black handles.

When needed, not only does the jig remove, but the router fence comes off as well. This leaves the router table open as an extension wing of the table saw, allowing 36.5" of rip capacity.
The table saw fence can move all the way over to the right.
