cluster kustomizations not used when using az cli?

[RoFz]

I have just deployed a new AKS and it seems that the contents of the clusters/ directory are not being used by flux when it gets deployed via az cli using the command included in this repo's README:

az k8s-configuration flux create -g flux-demo-rg -c flux-demo-arc -n cluster-config --namespace cluster-config -t connectedClusters --scope cluster -u https://github.com/Azure/gitops-flux2-kustomize-helm-mt --branch main  --kustomization name=infra path=./infrastructure prune=true --kustomization name=apps path=./apps/staging prune=true dependsOn=["infra"]

If I look for kustomizations in the cluster, I can not find any other than those referenced in the az k8s-configuration flux create command:

NAMESPACE        NAME                   AGE   READY   STATUS
cluster-config   cluster-config-apps    43m   True    Applied revision: main@sha1:3dbc5deb98d5a8099d06def8f40628ab103b0330
cluster-config   cluster-config-infra   43m   True    Applied revision: main@sha1:3dbc5deb98d5a8099d06def8f40628ab103b0330

Is that correct (that the clusters/* kustomizations are not used)?
