Is there a use of that?
A little story:

DRAWING_VECTOR[1] = new GraphicsPath(Vector.<int>([5, 5, 2, 5]), initPathData);
//DRAWING_VECTOR[1] = new GraphicsPath(Vector.<int>([2, 3, 2, 3, 2]), initPathData);

I have created a rounded square on one side and I want to get rid of curveTos in some situations and make it maximally optimized.
So I thought to have

Vector.<int>([5, 0, 5, 5])//3 lineTos instead of earlier 4.

But it doesn’t work and creates slightly different line than here (a note: each line gives the same effect)

Vector.<int>([5, 5, 0, 5]);
Vector.<int>([5, 5, 5]);
Vector.<int>([0,5, 5,0,0,0, 5,0,0,0,0]);

Here is whole code:

  private static  const DRAWING_VECTOR:Vector.<IGraphicsData> = new Vector.<IGraphicsData>(3, true);
  DRAWING_VECTOR[0] = new GraphicsGradientFill(GradientType.LINEAR, [0xFFFFFF, 0xFFFFFF], [.1, .75], [0x0F, 0xF0], matrixButton, SpreadMethod.REFLECT, InterpolationMethod.RGB);
  //DRAWING_VECTOR[1] = new GraphicsPath(Vector.<int>([5, 0, 5, 5]), initPathData);
  DRAWING_VECTOR[1] = new GraphicsPath(Vector.<int>([2, 3, 2, 3, 2]), initPathData);
  DRAWING_VECTOR[2] = new GraphicsEndFill();
  private static  function get initPathData():Vector.<Number> {
   var data:Vector.<Number> = new Vector.<Number>(14, true);
   data[0] = data[2] = data[13] = 0;
   data[1] = data[11] = BaseWindow.BAR_HEIGHT * 4 / 9;
   data[3] = data[5] = data[7] = data[9] = BaseWindow.BAR_HEIGHT * 2 / 3;
   data[4] = -BaseWindow.BAR_HEIGHT * 2 / 9;
   data[8] = data[10] = data[12] = -BaseWindow.BAR_HEIGHT * 1.5;
   data[6] = data[8] - data[4];
   return data;
  }
