Logically, they will show you whatever is most likely to generate revenue (possibly amortized over time). As long as the probability of you reordering is higher

Logically, they will show you whatever is most likely to generate revenue (possibly amortized over time). As long as the probability of you reordering is higher than that if you buying a random item out of millions (and those odds are tiny to begin with), the logical thing to do is to show you the item you already ordered.
