Alright. It does appear to be at a Battle.net level, so if you are active on any license, it resets the timer for name release. I believe it’s worked that way for awhile but we didn’t have it specified
Of course, this is subject to change, as we are working to try to be as fair as possible to those who want to reserve specific names and also those who want to use a name that may have well been completely forgotten by the original user. If anything changes we’ll update that article to reflect it.
