Atomically update multiple documents

In mongodb, I have the following command to update a bunch of documents

I am using mongodb-native driver for Node.js:

champion_statistics.bulkWrite([
    {updateOne: {filter: {id: 1}, update: {$inc: {sum: 2}}, upsert: false}},
    {updateOne: {filter: {id: 2}, update: {$inc: {sum: 5}}, upsert: false}}
], {
    ordered: false
}, function(err, res){
    //done
});

However, when I do a read, I find the collection in a state where the first operation finished but not the second operation. Is there something I can do to make multiple updates atomic?
