Problems with multiple update in MongoDb

I have mongo structure like this:

{
        "_id" : ObjectId("51596b7e469b9c3816000001"),
        "company" : {
                "_id" : "ade2fd0ec9b8b5e9152e0155",
                "title" : "LO3426546457"
        },
}
{
        "_id" : ObjectId("51596cef469b9c3816000008"),
        "company" : {
                "_id" : "ade2fd0ec9b8b5e9152e0155",
                "title" : "LO3426546457"
        },
}
{
        "_id" : ObjectId("51596cc3469b9c3816000007"),
        "company" : {
                "_id" : "ade2fd0ec9b8b5e9152e0155",
                "title" : "LO3426546457"
        }        
}

And I want to change all 'title' fields for objects with a specific '_id'. I do like this:

Collections.UsersCollection.update({
    'company._id': 'ade2fd0ec9b8b5e9152e0155'
}, {
    $set: {
        'company': { _id: 'ade2fd0ec9b8b5e9152e0155', title: 'blablabla' }
        // I also tried: 'company.title': 'blablabla'
    }
}, false, true);

And after execution that code in Node.js (I use node-mongodb-native), mongo updates only one document.

But if I do that command at Mongo Shell (mongo.exe), everything works fine and updates all documents.

What's the problem?
