I'm assuming they were also compressed.  Depending on the
compression scheme, if there is a lot of text (words, phrases)
that are shared between the documents then closely related
text should compress better then more distantly related text.

But that makes a lot of assumptions on the compression, like
that it doesn't reset itself after a given amount of data.
