Is there a shortcut or script to toggle the Clone Tool's Flip Horizontal and Flip Vertical states?

I've tried different ways and it doesn't seem to be possible to change the flipX and flipY brush options. The script works without errors, the object is changed, however, at the moment the set command is applied, these parameters are ignored. ¯\_(ツ)_/¯

#target photoshop
var s2t = stringIDToTypeID;

(ref = new ActionReference()).putProperty(s2t('property'), p = s2t('tool'));
ref.putEnumerated(s2t('application'), s2t('ordinal'), s2t('targetEnum'));
var cTool = executeActionGet(ref).getEnumerationType(p);

if (cTool == s2t('cloneStampTool')) {
    var brush = executeActionGet(ref).getObjectValue(s2t('currentToolOptions')).getObjectValue(s2t('brush'));
    (r = new ActionReference()).putEnumerated(s2t("brush"), s2t("ordinal"), s2t("targetEnum"));
    (d = new ActionDescriptor()).putReference(s2t("target"), r);
    d1 = new ActionDescriptor();
    d1.putBoolean(x = s2t("flipX"), !brush.getBoolean(x)); //nothing changes
    d1.putBoolean(y = s2t("flipY"), !brush.getBoolean(y)); //nothing changes
    d.putObject(s2t("to"), s2t("brush"), d1);
    executeAction(s2t("set"), d, DialogModes.NO);
}
