Trying to recreate an adaptive component laid out on a divided surface

[polylop]

I'm trying to recreate this (https://www.youtube.com/watch?v=umTSYgDir9s). Seems really easy in revit and I'm well aware that these types of things are better done in Dynamo.
What caught my attention though was the unusual way the adaptive component propagated (i.e. from the tutorial, it appears like the components had the same point1).

I tried to recreate the tutorial but all I got was spheres of the same size (after clicking repeat), I'm quite sure I've followed the tutorial and I've tried redoing it a couple of times already. Any idea why this happens?

Zach is using a an adaptive as a driver for the diameter of the sphere based on the distance of the a point to the relative grid point.
ie you're missing a step.
Check out this video in which he shows you how to set up the rig to get the reactor to function correctly.

Thanks!
Just a quick question - I'd probably watch the whole video at some other time because I'm going through all of zach's tutorials. For now though, what timestamps do I need to watch?

Reactors start about the 30 min mark.
I think he starts creating that reactor family about the 37 min mark
