As a guess, I think he may have meant that it adds the file to all the
folders, and then compresses the folders.  The folder that shows the
smallest increase in size (after compression) is the 'correct' folder.
The idea being that the compressor will exploit redundancy, and that
redundancy correlates highly with being in the 'correct' folder.

Obviously, this is speculation.  Hopefully Jeff will clarify what he
meant.
