In my experience the manufacturer has in his "update" software the whole control whether he wants to delete only user data, or everything before he update the device.
But IMHO to avoid any trouble during the update, they prefer to delete everything. I.E. they could run into trouble with already set persistent system variables or already existing Shared Preferences and other dangling things like sysfs entries and so on. And I could also imagine that they want to force the user to make his system settings again ( Language, Time , Emails clients, Home Screen and so on ..) Best regards !
