Legacy servers don't report nModified for updates, and it is impossible for the driver to simulate it: nModified must be equal to the number of documents that are actually different after an update, but legacy servers only report the number of documents matched. PyMongo must therefore omit the nModified field from a Bulk API result when talking to a legacy server.
