I think this has something to do with how jobs with the same name are saved in job.export().

await job.export();

// Since all 3 jobs have the same file name, and exportOne() is called concurrently on
// each job, 2 of the jobs may have to call createUniqueFilePath() a second or
// third time. This race condition means there is no order to the file names.
