Amazon's algorithms are so complex as to be trade secrets. We do know that Amazon uses what's known as the "nearest neighbor" technique when attempting to produce reliable ideas for what you might like. For instance let's say you look at products x1, x2, and y1; Amazon will use its advanced algorithms to compare you to pretty much everyone else who has looked at or purchased those products, determine any similarities, and offer you a suggestion based on that. This is the same model used by netflix, coincidentally.
So.. normally really weird stuff like this occurs when the data is basically just screwy. Which is to say that a relatively small sample of people have viewed that product meaning that Amazon doesn't really have a statistically significant based with which to compare you to—hence, bad recommendation.
