If you're naming a document for human consumption, having the files sorted by date easily without relying on modification date (which is changed by fixing a typo/etc...) is pretty neat
So you can't sort by name, author etc? One sort key? What year is it?!
This is exactly it - file name is easy to control and sort on; creates date and modified date are (for most users) random and uncontrolled.
