All differences are detected only when info.version is equal for compared documents

I use following swagger spec:

{
  "swagger" : "2.0",
  "info" : {
    "version" : "1.0.10",
    "title" : "dummy-service"
  },
  "basePath" : "/",
  "tags" : [ {
    "name" : "multipart-support-service"
  }, {
    "name" : "protocol"
  }, {
    "name" : "protocol-v2"
  } ],
  "paths" : {
    "/protocol/version-2/message-changed" : {
      "post" : {
        "tags" : [ "protocol-v2" ],
        "summary" : "Receive operation for protocol service version 2",
        "description" : "This operation is also very important",
        "operationId" : "IProtocolServiceV2_receive_POST",
        "consumes" : [ "application/json" ],
        "produces" : [ "application/json" ],
        "parameters" : [ {
          "in" : "body",
          "name" : "msg",
          "description" : "message to process as Message object",
          "required" : true,
          "schema" : {
            "$ref" : "#/definitions/Message"
          }
        }, {
          "name" : "User-agent",
          "in" : "header",
          "description" : "User-Agent header parameter",
          "required" : true,
          "type" : "string"
        } ],
        "responses" : {
          "200" : {
            "description" : "successful operation",
            "schema" : {
              "$ref" : "#/definitions/Message"
            }
          },
          "400" : {
            "description" : "Invalid arguments passed"
          },
          "404" : {
            "description" : "Something was not found"
          }
        }
      }
    }
  },
  "definitions" : {
    "Message" : {
      "type" : "object",
      "required" : [ "message", "protocol-type" ],
      "properties" : {
        "message" : {
          "type" : "object",
          "description" : "message to process",
          "additionalProperties" : {
            "type" : "object"
          }
        },
        "protocol-type" : {
          "type" : "string",
          "example" : "OLD",
          "description" : "type of protocol",
          "enum" : [ "OLD", "NEW" ]
        }
      },
      "description" : "message type"
    }
  }
}

then I change /protocol/version-2/message to /protocol/version-2/message-changed to create new file and run following command:
target\node\node.exe target\node_modules\swagger-diff\bin\swagger-diff.js swagger-previous.json target/classes/docs/restapi/swagger-new.json

When versions are the same for both files (1.0.10) the result is as expected:

Errors (2)
delete-path                   /protocol/version-2/message - Deleted
add-path                      /protocol/version-2/message-changed - Added
Warnings (0)

When versions are 1.0.10 (previous) and 1.0.11 (new) the result is:

Errors (1)
delete-path                   /protocol/version-2/message - Deleted
Warnings (1)
add-path                      /protocol/version-2/message-changed - Added

For 1.0.10 and 1.0.11-SNAPSHOT the result is:

Errors (0)
Warnings (0)
