JsonPath SelectToken not working for recursive structure

I have the following JSON on which I want to get specific values using SelectToken -

{
  "Result": {
    "Id": "knownvalue0",
    "Name": "Level0",
    "Children": [
      {
        "Name": "Level1",
        "Id": "knownvalue1",
        "Children": [
          {
            "Name": "Level2",
            "Id": "knownvalue2",
            "Children": [
              {
                "Id": "knownvalue3",
                "Name": "Level3",
                "Children": []
              }
            ]
          }
        ]
      }
    ]
  }
}

The structure is recursive and I do not know the depth at runtime. However I do know the Ids and want to verify that the names are correct. So I use a JsonPath like this - Result..[?(@Id=='knownvalue')].Name in jtoken.parse(response).selecttoken(jsonpath) method. A problem is occurring when I am using this jsonpath on knownvalue1 or knownvalue2 i.e -

Result..[?(@Id=='knownvalue1')].Name

I am getting exception - Path is returning multiple tokens. Why is the selecttoken returning multiple tokens even though there is only 1 name with Id = 'knownvalue1'?? The Level2 and Level3 nodes are children, they should not be returned.
