Touchscreen recognized as touchpad with hid-multitouch driver

Thanks for pointing me at this, I was not fully aware of it. 

However the question still remains why the pointer is still visible. Of
course I could remove it or do the usual tricks like setting it to an
invisible pixel. My understanding however was that the pointer is not
shown if only a touchscreen is detected.
 
Perhaps this assumption is wrong or there are some conditions for this I
did not get.
