Hmm. Well kind of, but it doesn't divert torque to the wheel with the most traction it just stops the wheel with the least amount of traction from spinning wildly so it dissipates the torque on that side by driving it againts the brake, i.e. the car bogs down but is controllable. If you know how a clutched LSD works then I'm surprised you think it's similar.
Anyway, 313 wheels are great so will give it a new lease of life
