why compare function return the same value

[loverains]

in updatemanager.cs,
   static int Compare (UpdateEntry a, UpdateEntry b)
   {
      if (a.index < b.index) return 1;
      if (a.index > b.index) return 1;
      return 0;
   }
this is comparer for sorting,why return the same value on differrent situation?

Bug! Thanks for pointing it out.

in uibuttonkeys.cs

case KeyCode.Tab:
            if (Input.GetKey(KeyCode.LeftShift) || Input.GetKey(KeyCode.RightShift))
            {
               if (selectOnLeft != null) UICamera.selectedObject = selectOnLeft.gameObject;
               else if (selectOnUp != null) UICamera.selectedObject = selectOnUp.gameObject;
               else if (selectOnDown != null) UICamera.selectedObject = selectOnDown.gameObject;
               else if (selectOnRight != null) UICamera.selectedObject = selectOnRight.gameObject;
            }
            else
            {
               if (selectOnRight != null) UICamera.selectedObject = selectOnRight.gameObject;
               else if (selectOnDown != null) UICamera.selectedObject = selectOnDown.gameObject;
               else if (selectOnUp != null) UICamera.selectedObject = selectOnUp.gameObject;
               else if (selectOnRight != null) UICamera.selectedObject = selectOnRight.gameObject;
            }
            break;

i think this one also a bug,we should replace the last selectonright to left
