Cosmos DB - Indexing Policy Settings

Question

I am using the azure cli in order to set my indexing policy. I am using the following JSON:

{
  "indexingMode": "consistent",
  "automatic": true,
  "includedPaths": [
    {
      "path": "/ttl/?",
      "indexes": [
        {
          "kind": "Range",
          "dataType": "Number",
          "precision": -1
        }
      ]
    }
  ],
  "excludedPaths": [
    {
      "path": "/*"
    }
  ]
}

The script reports no errors have occurred, however when I log into the portal and look at the indexing policy, it shows the following:

{
    "indexingMode": "consistent",
    "automatic": true,
    "includedPaths": [
        {
            "path": "/ttl/?",
            "indexes": [
                {
                    "kind": "Range",
                    "dataType": "Number",
                    "precision": -1
                },
                {
                    "kind": "Range",
                    "dataType": "String",
                    "precision": -1
                }
            ]
        }
    ],
    "excludedPaths": [
        {
            "path": "/*"
        },
        {
            "path": "/\"_etag\"/?"
        }
    ]
}

The portal settings include an extra excludedPath and index, so I am not sure if this is intentional or I am doing something wrong. Or are the two equivalent?

Any help would be great!

Since indexing v2 came out the default indexing will add range for both strings and numbers and it will also automatically exclude the ETag.
