I can confirm that dofromon's issue is not the same issue that this topic is discussing.
First, I have never had this issue under Mavericks, where my laptop, my desktop, and my iPhone all had different notification settings. They were not cross-synced across iCloud. Dofromon seems to be misinterpreting the iCloud backup for iPhone, which saves most iPhone user settings and can restore them to the iPhone on request: but, it does not push these settings to other operating systems or devices.
Secondly, my settings on my iOS device are not being copied to my computers, even though all of my devices sync across iCloud. The Notification panel settings for my iPhone 5S running iOS 8.1 are not being copied to my desktop and my laptop.
For example, the things that I have on my iOS device are set to banners only, silent, maximum notifications (and everything else is turned off), but my computer is turning everything on, with badges sounds and banners, and resetting everything to 5 notifications.
When my computers are disconnected from the internet and prevented from connecting by disabling my router, they still reset their settings on reboot: so they are definitely not downloading the default OS settings from iCloud.
