If your cluster is setup correctly (with proper value set for discovery.zen.minimum_master_nodes) they shouldn't. But if you are running without discovery.zen.minimum_master_nodes set, they might indeed form a new cluster. Obviously some shards might end up in one cluster and not in the other and if you are indexing while this is happening you will lose some data. I would say it's pretty..... extreme way to test full cluster restart.
