I agree, it doesn't answer your question, but using 1 roto with a translate of 1 eye is doing the same thing in a simpler way.

I cant answer it directly but isn't this the same as having one shape and adding a split transform node underneath
(ie split the translate knob and adjust position for the other eye)

    *Subject:* [Nuke-python] Linking pairs of bezier shapes

    I have sets of bezier shapes, exact copies other than one is
    shifted horizontally from the other. Ie "Bezier1_Right" and
    "Bezier1_Left". Is there a way to have one shift accordingly when
    the other is changed?

    I have gotten this to work by using a save and update method where
    I have funtions that first save the data for the shape, look at
    the difference between the original and the new, and then apply
    that difference to the pair. I'm trying to work this into a
    callback but I've run into an issue where this method no longer
    works because the callback happens over and over again as I move
    it so it registers no change in movement.
