How to setup MotionVector in maya?

mv.zip1. I've follow the online help MotionVector AOV and MotionVectorshader ,but i found that the position of object is not match to the viewport unless i set the Position to 'Start On Frame';

2. MotionVector&MotionVectorShader AOVs is not work in Nuke no matter how i tweak the setting in MtoA, but Redshift MotionVector work fine in Nuke ,same maya file.

So what is the exact right way to setup MotionVector for both deformation & transform object?

I'll attach my simple maya file and please help me out if you can solve it.

It's a Nuke bug. Save the comp and reload it. If that doesn't change things, then restart Nuke.
