This might be true, but I'm not sure if it is true. If so, the user
would get the old app release, instead of a new release. I suspect that
it's not a diff, but just the purchase meta-data and that the app is
downloaded again, but I might be mistaken here, while I'm definitively
not mistaken with the user data. Again, you synced without accidentally
deleting the app first. Such a sync is not a backup. A real backup would
allow to restore data, even if the app was accidentally deleted and then
reinstalled.
