Here is the answer from a Minikube contributer, confirming there was a problem in the documentation :
I've reworded the readme to make a little more sense.
The host is the computer you're running minikube on. This is only exposed to the VM through the mounted host folders https://github.com/kubernetes/minikube/blob/master/docs/host_folder_mount.md
The guest, or minikube VM, will persist certain folders to a disk stored on the host (something like ~/.minikube/machines/minikube/disk.vmdk). Files stored in certain directories in the minikube VM will persist between start/stops, but not deletes.

This is covered in the documentation. The relevant section starts right after the sentence that you've already quoted:
However, Minikube is configured to persist files stored under the following host directories:
Here is an example PersistentVolume config to persist data in the ‘/data’ directory:
apiVersion: v1 kind: PersistentVolume metadata: name: pv0001 spec: accessModes: - ReadWriteOnce capacity: storage: 5Gi hostPath: path: /data/pv0001/
hostPath volumes that are mapped to any directory in
/data on the host, and these should persist across reboots.
