Script for switching brush spacing on/off

Hi! I found a script that switches the brush spacing in this post https://community.adobe.com/t5/photoshop-ecosystem-discussions/q-brush-s-spacing-setting-for-get-set-or-ignore/m-p/9468530 . 

But when it switches, it resets the brush to the default settings. Is it possible to switch without resetting the brush? Here is this script by r-bin

function get_brush_space_checkbox()

    {

    try

        {

        var r = new ActionReference();

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

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

        var ret = executeActionGet(r);

        ret = ret.getObjectValue(stringIDToTypeID("currentToolOptions"));           

        ret = ret.getObjectValue(stringIDToTypeID("brush"));           

        ret = ret.getBoolean(stringIDToTypeID("interfaceIconFrameDimmed"));           

        return ret;

        }

    catch (e) { alert(e); }

    }

        desc.putObject( charIDToTypeID( "T   " ), charIDToTypeID( "Brsh" ), desc1 );

        executeAction( charIDToTypeID( "setd" ), desc, DialogModes.NO );

        ref = null;

        desc = null;

        desc1 = null;

        }

    catch (e) { alert(e); throw(e); }

    }
