Maybe the example was poorly picked but the point stands: if you're asking for a sorted set based on a comparator, you should expect duplicate elements as dictated by comparator to be eliminated. If you wanted to sort a set of people by age, you wouldn't use a sorted set but a sorted sequence. That is what sort/sort-by provides.
