Note that the hosted control plane namespace is still different for both clusters.

Customer is just following the doc - https://access.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.9/html/clusters/cluster_mce_overview#creating-a-hosted-cluster-bm for both the clusters and only the hostedcluster CR is created in the same namespace.

    2. Create another hostedcluster in the same namespace where the first hostedcluster was created.
    3. Second hostedcluster fails to proceed with the said error.
