This is my read too, since they're citing Judge et al versus the characters or the characters' papers. Its the same vein as when Dropbox's Lepton article cited middle-out as a humorous attempt at self-promotion.
So you think they would put a humorous reference to a TV show in the synopsis of their groundbreaking image compression paper and again as an academic reference in their paper?
This whole thread is like being the only sane person in an asylum.
Also, it isn't a 'real implementation' since there isn't any source code to reproduce the results.
