LT1236 trim as negative reference

I understand that the LT1236 can act as a negative reference by controlling the voltage drop across an external resistor placed between the negative rail and the GND pin of the LT1236. If a trimpot is placed between LT1236's VOUT, TRIM and GND pins in the same way it would be when the LT1236 is used as a positive reference, does it perform the same trimming function? Or is there some other subtlety involved?
