Multi-Aim Constraint limits don't work

I've been playing with the ninja sample to get a better understanding of the Animation Rigging package. First of all, I would like to thank you, I like the package a lot.
Secondly I have a couple of questions concerning the Multi-Aim Constraint:
1-Shouldn't there be limits for each axis depending on "Constrained Axes" ?
2-I faced the following issue regarding the limits:
I tried dragging the target behind the character which resulted in the artifact below so I exited play mode and played with the limits of the Spine Constraint (Right Inspector) but they don't seem to work on the Spine Ctrl (Left Inspector). Am I missing sth ?

 

Ohh, I checked the code to find that the "Limits" apply to the rotation delta not clamping the final rotation value. I guess I got confused there..

Code (CSharp):

1. var rotToSource = Quaternion.AngleAxis(
2.                         Mathf.Clamp(Vector3.Angle(currentDir, toDir), minMaxAngles.x, minMaxAngles.y),
3.                         Vector3.Cross(currentDir, toDir).normalized
4.                         );
