Feature refinement levels redundancy

Hi Everyone.

I can't understand why people uses refinement in "features", and then uses the same level refinement in the same feature in "refinementSurfaces"?,

For intance, in a tutorial has someting like this :

Code:

castellatedMeshControls

{

 

  features 

    {..

     {file "wall12.eMesh"; level 3;} 

    };





  refinementSurfaces 

    {...

     {file "wall12.eMesh"; level 3;} 

    };

}

is this not redundant? avoiding this in some way can make more efficiency the time to make a mesh?
