How to swap Pin in 1 component

I want to swap pin (change only x y position of pin, pin number and pin name remain unchanged) in the same component together.

This my code but it not work, can someone check where i made a mistake:

println("PLEASE SELECT 1ST PIN")

first_pin = car(axlGetSelSet())

first_xy = (car(axlGetSelSet())->xy)

axlClearSelSet()

println("PLEASE SELECT 2ND PIN")

second_pin = car(axlGetSelSet()

second_xy = (car(axlGetSelSet())->xy)

axlClearSelSet()

axlCompMovePin(first_pin , ?move second_xy)

axlCompMovePin(second_pin , ?move first_xy)
