No, they were actually over the speed of light for a "portion of the signal": "They were also able to create extreme conditions in which the light signal travelled faster than 300 million meters a second. And even though this seems to violate all sorts of cherished physical assumptions, Einstein needn't move over relativity isn't called into question, because only a portion of the signal is affected."

Okay, guess I should have read the article first, given the title is "Light that travels faster than the speed of light"

Perhaps they are referring to being able to vary the speed while it is below the speed of light. That is, slowing it down to 1/10th the speed of light, and then speeding it up to 1/5th the speed of light.
