Involute spline definition 2

[Art06]

I am reviewing a part with a metric involute spline. One tolerance specified is a "radial circle jumpiness tolerance". Is this another way of saying radial concentricity? If not, what does it mean? Thanks

It's been a while since I have looked at metric specs, but refer to the Bosche Automotive Handbook. It gives excellent descriptions on this.
