It looks like they try to mimic some Dark Wallet features, but they do the mixing in a different way that looks like have into consideration the dead change problem Aswan detected and eduffield + UdjinM6 solved. Besides the post that is linked in the article about how they do it, they have published another one after that in which they give some more information:

They don't fully describe, but apparently what they do is divide the change into a random number of transactions, randomize their order and avoid using two of them in any future transaction together. I think our change contracts with atomic transfers are better, but this is also nice.
