From a PT stand point, this saddle is seems like a very bad idea. Anatomically, the sit bones are intended to take weight, yes they get sore if they weight bear more than they are used too, on a different part of the bone than they are used to, or on a different (usually harder surface). But, your muscles are not intended to bear the weight of your body with direct pressure. Can they? Sure for a little while if they are not being asked to contract or relax at the same time. It seems to me that there would be a fair bit of micro trauma to the muscle tissue if all your weight is suspended on the muscle-y bits while they are shortening and lengthening.
ETA: I just thought of another issue with this saddle. Saddles with large cut outs tend to break down more quickly than those without. I would think that would be an even bigger problem with this saddle. That's a pretty expensive saddle to have to replace every year or two.
