Because Scorers like the phrase scorers or IntervalScorer don't return positions, they return intervals, with a start and end.

> This change will allow Scorers to expose which positions within a document they have matched, via a new IntervalIterator interface.  Consumers get the iterator by calling intervals() on the Scorer, then call reset(docId) whenever the scorer has advanced and nextInterval() to iterate through positions.  Once all matching intervals on the current document have been exhausted, nextInterval() returns false.
