depends on what you're trying to do with your c/os. It looks like he's getting nearly a motion ratio of nearly 1:1. That'll limit your travel but will decrease the damping the shocks have to do for each increment of wheel travel.
The desert racing guys angle shocks so that they can get more wheel travel for each bit of travel of the shock itself - but the trade off is the shock has to work harder.
As far as that setup goes, i would not be surprised to hear that his (frame-side) link mounts broke after a rear wheel impact. Arms in bending! WHOO!
