Azure Enterprise Scale

Hi, I’m looking through these docs, currently here in the section where connectivity resources are deployed. Deploy the Microsoft Cloud Adoption Framework Enterprise-Scale Module | Terraform - HashiCorp Learn

I see that resources are created in a subscription called “Team Education” which resides under the root management group. For CAF enterprise scale architecture, this subscription needs to be moved under the Connectivity management group. This is how governance is applied. Also a different subscription needs to be used for management resources (previous section) and this sub needs to be placed under the Management management group.

Can you explain the thinking in the example here. Am I missing something?
