Yes, I wasn't aware of that either, but correct me when I'm wrong, but I was under the impression that they claim to have made light (photons) go faster than the speed of light using 'photon tunneling', hence the 'you (seem to?) appear before you start your travel' consequence. The two german scientists claim to have found (and proven) that there's an error in Einstein's special theory of relativity or at least an exception.

According to this:
While the peak moves faster than light speed, the total energy of the pulse does not. This means Einstein's relativity is preserved, so do not expect super-fast starships or time machines anytime soon.

The 4 times the lightspeed didn't "break" any laws of Einstein's special theory of relativity.
