[Brush angle and tilt]

In editing of brush can be used Angle and Tilt of stylus. But Angle uses only X axis of tilt of stylus and Tilt uses only Y axis. Is it feature or bug? I can't assign real tilt of stylus to brush.

Any suggestions?

 

Thanks

And second one: Is possible to set up brush rotation according to tilt of stylus AND randomly at the same time?
