RKE generated kube-proxy configuration

The RKE generated kube-proxy configuration indicates that the API server connection URL is on all nodes. I am trying to wrap my head around how this is supposed to work, especially in a HA environment with multiple controlplane/master nodes. The vanilla Kubernetes configuration produced by kubeadm for instance puts one of the master node as the server URL, but if you have multi-master setup you then go edit the deployment YAML and replace that URL with one that is load-balanced among the master nodes.

apiVersion: v1
kind: Config
- cluster:
    api-version: v1
    certificate-authority: /etc/kubernetes/ssl/kube-ca.pem
    server: ""
  name: "local"
- context:
    cluster: "local"
    user: "kube-proxy-local"
  name: "local"
current-context: "local"
- name: "kube-proxy-local"
    client-certificate: /etc/kubernetes/ssl/kube-proxy.pem
    client-key: /etc/kubernetes/ssl/kube-proxy-key.pem
