Root Motion Curves Problem and Animation Authoring

Hello there,

Yesterday i was messing around with the Animation Authoring feature as seen in this video: https://unity3d.com/learn/tutorials/modules/beginner/unity-5/root-motion-authoring .

It's easy to set it up but i'm having some problems with a real implementation.
I've created an example with Unity Webplayer (remember to use it with Firefox) : http://baenor.altervista.org/AnimationProblem.html

(Just press the Right arrow to move the cube)

As you can see i've created an animation that "bounces" from one cube to another. There are different keyframes in the animation but, you just have to know, that the first position keyframe starts at 0,0,0 while the last one ends at 1,0,0.

So i've set everything like the Unity Video Tutorial but as you can see from my demo, the cube ends in a different position : it is not 1,0,0 from my last one.

Why?
How can i solve this issue?

 

UP!
