I guess the reason is that the "lastDoc" is part of the iterator, but the "IndexSearcher" is not always the same, so that if there were changes in the meantime, the "lastDoc" does not correspond to this "IndexSearcher". This might mean the query result is sometimes wrong (matches are not returned, or returned twice).
