Locality in this sense refers to the presence of "hidden variables" as first put forth by bohm and later suggested by other people. It was believed that the various CHSH, HOM, and other bell-inequality inspired experiments would have put a nail in the coffin but critics always came back and say "but you didn't control for X." This experiment is just another in the long line of experiments started by Aspect and continued by others to put bounds on this.
It's like saying "Gravity violates conservation of energy!!!" No it doesn't; quit playing fast and loose with well-understood principles.
