There is absolutely a reason. A user queried for a string, then followed a link. Biasing Bing's search results towards the followed links is a signal that improves their search.

When I took exams, I wasn't allowed to consult with fellow students, read the internet, or open a textbook. My life as a developer would certainly be a lot different if I wasn't able to do any of those things now because it was "cheating" back when I was in school. It's an awful analogy and, as you've regurgitated it here, seems to be an effective smokescreen on Google's end.
