Unnecessary code in method "object_add_child_node"?

Error on this method (which doesn’t seem to have impact, maybe in performance with large data it could)

Shouldn’t the method insert only to OBJECT_CHILDREN (and not append to ARRAY_CHILDREN, which is what ARRAY_ADD_CHILD_NODE does…)?

  METHOD object_add_child_node.
    DATA : wa_array_children TYPE lcl_mdp_json_node=>typ_array_children .
    wa_array_children-node = child_node .
"IS THIS APPEND NECESSARY?
    APPEND wa_array_children TO me->array_children.
    DATA : wa_object_children TYPE  lcl_mdp_json_node=>typ_object_children .
    wa_object_children-key = child_key .
    wa_object_children-node = child_node .
    INSERT wa_object_children INTO TABLE me->object_children.
    object_node = me.
  ENDMETHOD.                    "object_add_child_node
