Review comment:
       I think we can keep here the same code as before just modify the 
starting `docID` as:
   
   ```java
   public DocIdSetIterator competitiveIterator() {
         if (enableSkipping == false) return null;
         return new DocIdSetIterator() {
           private int docID = competitiveIterator.docID();
   ```
