What did the error correction report -- is it valid on a byte level? They might use a new highlevel encoding, but I doubt it, and they are certainly not re-inventing the error correction level. This stuff is hard math and there is no value in re-inventing that.
The higher level might be encrypted to prevent fraud, but that would show as valid on the error correction level.
Other than that, my first guess is that the image shown there is not an actual data matrix code but a fake image made for the web site.
On a second thought, they might have used a simple pseudo-encryption (read: security through obscurity) on a lower level, such as flipping the inner pixels. But then again, this means you cannot use standard tools for anything, so I doubt it.
