Follow an animated target in camera target mode?

Hi,
I have an animation playing that I want the viewer to be able to orbit around, but the camera target position needs to change throughout the animation. Basically I want the "SetCameraMoveStyle" node to get the target position continually. However, despite the target being animated in an NLA strip, the camera only focuses on its position on the first frame of the animation.
Is it possible to do this?

I've attached and example. Is this what you want to achieve?
Note that there are two approaches:
1) using Set Camera Move Style node (the entry point is muted)
2) using Move Camera node
The second approach has more smooth result because it has less calculations which could cause data lost and thus cause twitching.
