AutoInput Automated touch cancels all other touchs(no multitouch)

Hello,

I am using tasker to map a hardware key to a touch that is hard for my fingers to get to but I need to be able to multitouch with it.
The problem is that autoinputs stimulated touch cancels all other touches. Is this phenomenon something specific to my device(note 9 exynos) or the fact that multitouch isn't supported?

You can see the effects by enabling show pointer in developer settings.

Also, is there anyway so that the touch is held down as long as he button is held?
Edit: I mimicked that behaviour by making two profiles, one on key down and the other on key up, and two tasks, one to start the clicking in a loop and
the other to stop the loop by setting a variable to a number. The only thing left is the multitouch thing and bingo!

Have a good day.

This happens if I hold a touch somewhere and then run the task.
I really don't know much about the android api or how it handles touch, so I can't debug it.
Thanks, have a good day/night.
