If I'm understanding the Lugcentric balancer correctly, the back of the wheel is supported by a cone on the balancer, the threaded shaft goes thru the center cap hole, but does not touch it, and the Lugcentric tool, attached to the threaded shaft, applies the pressure back holding the wheel against the cone in the back of the wheel, while also supporting the wheel concentric via the 5-lug holes?

Sort of. The five, mini-cones only engage with the five lug holes. That's all that is engaging with the wheel. Depending on the machine a center pilot may be used to retain the wheel to the five pilot adapter.
