I looked hard, and could not prove they can identify a single image with that accuracy. I couldn't tell WHAT the trial protocol was. Where is that in the document?
The LFW test is verification: given two faces you've never seen before, tell whether they're the same person or not. That's a much weaker test than saying "who is this?"
The LFW benchmark protocol is described in the original tech report: http://vis-www.cs.umass.edu/lfw/lfw.pdf
