How to use "Update_Trigger" to change haptic style of a named trigger?

Trying to optimise AQT's haptics setting system to be more efficient when running, but my idea to use Update_Trigger applescript method to switch an action between haptic styles "None" and "Strong" doesn't seem to be working... Does anyone know how this could work?

It seems like it isn't switching the action at all...

Haptic is supposed to be fired when you hold the "Hold here button" and the haptics is checked, then should not fire when haptics is unchecked.
