As described in the post, this seems quite analogous to the operation of a bloom filter, except each "bit" is more than a single bit's worth of information, and the match detection has to do some thresholding/ranking to select a winner.
That said, the post is itself clearly summarizing much more technical work, so my analogy is resting on shaky ground.
