This machine have 2 separate buzzing motions per 1 command :
1)- Main motion.
2)- Motion to the middle position.

In addition:

3)Therefore this turnout has an unnecessary, excess move if accepts command to swich into the same position.

"2" and "3" - Is not so realistic buzzing!!!

Video Demonstration:

May be another methods of cancellations exists?
How to cancel excess motion to the same position?
