Correct.
I tested both the Toggle Throttle Reverse Thrust and Hold Throttle Reverse Thrust functions.
In the case of Toggle, the animation and reverse function are correct.
In the case of Hold, the animation is 100% incorrect, but function is correct.
I hope that makes sense. The video illustrates the animation of each type (Hold and then Toggle). It is plainly clear how anyone observing the throttles during the configuration/setup operation would think that Hold was not going to work.
