Maybe it is the way that the author has worded it but he seems to suggest that the Azura device is the first WEC to absorb wave energy from both up and down and side to side motion.

Ceto buoys are multidirectional as well.  

Stonehenge's Protean device is another.

"The buoy, named Azura, absorbs wave energy from both up-and-down and side-to-side motion, the first design of its kind."
