I am using Max 2014 and when I add the x-form modifier, enter the gizmo sub object and move it, the spline moves as well, so doesn't work as per the video, when you want to move the splines pivot point


?
So, at least for me and in Max 2014, I cannot adjust the pivot point of the spline, using the XForm modifier
Any ideas why this is not working?
EDIT
Sorted.. I missed the fact that you rotated the offset splines by 30 degrees, in the Z axis.
HOWEVER, you incorrectly stated that the XForm modifier is moving the pivot point, it is actually moving the original spline BUT the pivot point remains in it's original place. So you are offsetting the spline from it's pivot point.
Suggestion, perhaps you could add a pivot point translation section, so negating the need to use xform altogether
