If you mean the 'Top Answerer', that list has not been updated in 4 months or more, so the information is outdated. Once the list is updated, that person may not be there any more.
However, if they still have the MOST Best Answers, they will still top the list. Whether they get those Best Answers due to voting or to being chosen by the asker does not matter. Only the actual number of Best Answers is counted.
