The mechanism is quite easy: It searches Google for random words and picks random pages among the results, then spiders from there (well it is spidering except that it only follows one URL at a time within a session thus simulating a user).
There's a few things wrong with this approach. Most of them were outlined by Bruce Schneier when he reviewed "TrackMeNot"[1] last year.
The same issues with TrackMeNot apply to Hayneedle, including potential false positives, and list of word combinations that can be filtered out easily, and well, the list goes on.
