No it wouldn't. I was refering to XInput, protocol version 2, to say that this property is an XInput property, and not a driver (evdev…) property, like 'Evdev Axes Swap'; which is broken in ubuntu, but utouch team told me migrate to the new 'Coordinate Transformation Matrix', which also happen to be broken.
So, I was indeed referring to device 9 (see xinput.txt)

I'm afraid this is another problem, I'd even say a it's a feature
request. For now you just do a for loop on all devices and apply the
appropriate coordinate transformation matrix.

For example (untested) :
ROTATION="left"
MATRIX="0 -1 1 1 0 0 0 0 1"
xrandr -o $ROTATION
for dev in $(xinput list |grep "slave  pointer" | sed -e 's/^.*id=//' | awk '{print $1}')
do
   xinput set-float-prop $dev "Coordinate Transformation Matrix" $MATRIX
done

Cheers :-)
