How to change reference plane normal direction in SolidWorks using SolidWorks 2016 API?

Question

API

A Reference Plane is created using the appropriate InsertRefPlane method , which takes only 6 parameters (2 parameters for each reference), while there is also the "Flip normal" option when building manually.

You can also change the normal manually on an already constructed plane. When you try to change the direction of the normal on an already constructed plane, nothing happens.
C# code:

swRefPlane = (RefPlane)swFeatureManager.InsertRefPlane(8, 0.05, 0, 0, 0, 0); // создание плоскости со смещением
swFeat = swRefPlane as Feature;
var data = swFeat.GetDefinition() as RefPlaneFeatureData;
data.AccessSelections(swModel, null);
data.ReverseDirection = true;
swFeat.ModifyDefinition(data, swModel, null);

How to change the direction of the normal of the plane (Reference Plane) using only the API ?
