The single shock underneath controls the pitch motion, as the whole mounting rotates on the bearings across the horizontal axis (can see bearings mounted like the recent ARB trends), and acts to only compress this shock, not the roll damper.
In roll, the links cause the central part of the housing to rotate around a vertical axis, which then makes the roll damper (the central round section with the small black springs either side) slide side to side, compressiong the small springs. This bit is effectively replacing the arb.

The system is basically a small scale version of what goes on in full size race cars with a triple damper setup, like f1 and LMP (although f1 has progressed to hydraulic springs with inerters these days), where the pitch and roll damping can be tuned independent of each other. Pretty trick setup IMO.
