Flip the smart object on the Y or X axis

There is a script like this (thanks to r-bin), but I can't figure out exactly how to write data into it. How to find out which sequence of points.

change_one_warp_mesh_point_for_smart_object(2, 100,150);

function change_one_warp_mesh_point_for_smart_object(point_index, hor,ver)

    {

 try {

 var r = new ActionReference(); 

 r.putProperty(charIDToTypeID("Prpr"), stringIDToTypeID("smartObjectMore"));

 r.putEnumerated(charIDToTypeID("Lyr "), charIDToTypeID("Ordn"), charIDToTypeID("Trgt")); 

 var obj = executeActionGet(r).getObjectValue(stringIDToTypeID("smartObjectMore")) ;

 var warp = obj.getObjectValue(stringIDToTypeID("warp")); 

 // if there is no warp, we will not create a new one, 

 // since we need to specify 4x4 points for this, and we want to change only one

 if (!warp.hasKey(stringIDToTypeID("customEnvelopeWarp"))) return false;

 /////////////// changing one point in the current warp mesh ////////////////////

 var meshPoints = warp.getObjectValue(stringIDToTypeID("customEnvelopeWarp")).getList(stringIDToTypeID("meshPoints")); 

 var new_meshPoints = new ActionList();

        

 for (var i = 0; i < meshPoints.count; i++)

            {

 if (i != point_index) 

                {

 new_meshPoints.putObject(stringIDToTypeID("rationalPoint"), meshPoints.getObjectValue(i));

                }

 else 

                {

 var d = new ActionDescriptor();

 d.putUnitDouble(stringIDToTypeID("horizontal"), stringIDToTypeID("pixelsUnit"), hor);

 d.putUnitDouble(stringIDToTypeID("vertical"), stringIDToTypeID("pixelsUnit"), ver);

 new_meshPoints.putObject(stringIDToTypeID("rationalPoint"), d);

                }

            }

 var customEnvelopeWarp = new ActionDescriptor();

 customEnvelopeWarp.putList(stringIDToTypeID("meshPoints"), new_meshPoints);

 warp.putObject(stringIDToTypeID("customEnvelopeWarp"), stringIDToTypeID("customEnvelopeWarp"), customEnvelopeWarp);

        ///////////////////////////////////////////////////////////////////////////////

 // execute transform command

 var d = new ActionDescriptor();

 d.putEnumerated(stringIDToTypeID("freeTransformCenterState"), stringIDToTypeID("quadCenterState"), stringIDToTypeID("QCSAverage"));

 d.putObject(stringIDToTypeID("warp"), stringIDToTypeID("warp"), warp);

 executeAction(stringIDToTypeID("transform"), d, DialogModes.NO);

        }

 catch (e) { alert(e); }

    }

 For example, through the Alchemist plugin, I can see the coordinates of these points. Maybe I should write them manually but swap them?
