My take on it is that it's good old keyword stuffing and dodgy at best.
The content is of absolutely no use to a human reader - there's no reason for them to care what other search terms led visitors to that page. And since it clearly looks like those phrases don't actually link to other articles (correct me if I'm wrong) they can't be considered "related content".
So a spammy tactic for SE manipulation only. If the site owner knows the page is targeted at those terms, he should be using them properly within the content instead of stuffing them at the end.
This is the kind of stuff Panda's been finding and killing for the past year or so. I sure wouldn't want to bet my rankings on it - and look like a douche to my readers in the process.
