I have Question of curve brush

It’s the first question.

If the curve brush deviates from the surface of the original mesh, it rotates.
I hope at least that it is turning towards the final direction that was attached to the original mesh
What should I do?
(I know how to manually rotate it after clicking on a curve and then clicking on the control, but doing it afterwards will eventually return to the previous state)

This is the second question.
