Incorrect highlight when using span_or query in span_near query

Elastic Stack Elasticsearch

Hello,
I have incorrect highlight when I use span_or query in span_near query. For example:
My index settings:

curl -XPUT 'http://localhost:9200/highlighting/' -d '{
    "settings": {    
        "analysis": {
            "filter": {
                "unique_filter": {
                    "type": "unique",
                    "only_on_same_position": true
                }
            },
            "analyzer": {
                "my_analyzer": {
                    "type": "custom",
                    "tokenizer": "standard",
                    "filter": [ "unique_filter" ]
                }                
            }
        }
    },
    "mappings": {
        "highlight": {                       
            "properties": {
                "Text": {
                    "type": "string",
                    "analyzer": "my_analyzer"					
                },
                "Id": {
                    "type": "string",
                    "index": "not_analyzed"
                }
            }
        }
    }
}'

Data:

curl -XPUT 'http://localhost:9200/highlighting/highlight/1' -d '{
    "Id":1,
    "Text":"Obama States President"
}'

I try to highlight by query:

curl -XPOST 'http://localhost:9200/highlighting/highlight/_search?pretty' -d '{
   "query":{
      "ids":{
         "type":"highlight",
         "values":["1"]
      }
   },
   "highlight":{
      "fields":{
         "Text":{
            "number_of_fragments":0,
            "highlight_query":{
               "span_near":{
                  "clauses":[
                     {
                        "span_term":{
                           "Text":"President"
                        }
                     },
                     {
                        "span_or":{
                           "clauses":[
                              {
                                 "span_near":{
                                    "clauses":[
                                       {
                                          "span_term":{
                                             "Text":"United"
                                          }
                                       },
                                       {
                                          "span_term":{
                                             "Text":"States"
                                          }
                                       }
                                    ],
                                    "slop":0,
                                    "in_order":true
                                 }
                              },
                              {
                                 "span_term":{
                                    "Text":"Obama"
                                 }
                              }
                           ]
                        }
                     }
                  ],
                  "slop":5,
                  "in_order":false
               }
            }
         }
      }
   }
}'

I get the result:

"<em>Obama</em> <em>States</em> <em>President</em>"

It is not true. 'States'should not be highlighted.
If I run the equivalent query:

curl -XPOST 'http://localhost:9200/highlighting/highlight/_search?pretty' -d '{
    "_source":false,
    "query" : {
        "ids" : {
                "type" : "highlight",
                "values" : ["1"]
            }
    },
    "highlight" : {
        "fields" : {
             "Text" : {
                "number_of_fragments" : 0,
                "highlight_query":{
                     "simple_query_string":{
                         "query": "President NEAR/5 (\"United States\" | Obama)",
                         "fields": ["Text"],
                          "default_operator": "and"
                     }
                 }
             }
        }
    }
}'

I get the correct result:

 "<em>Obama</em> States <em>President</em>"

There is problem in ES1.7.1-5.0.0-alpha2. I can not use a simple_query_string for my tasks. Can anybody help me?

Many thanks,
Alexander
