TFTP Proxy and duplicate device names

Question

With the TFTP Proxy feature added in CUCM 8.6(2), has anyone figured out what happens if the same device is configured on two different clusters?  Pre-8.6, CUCM had an ordered list of Alternate Cisco File Locations, so the first cluster on the list that had that device would serve the .cnf file.  But TFTP Proxy doesn'ty have an ordered list, so which cluster has priority?

I saw that document and read it before I posted.  And I poured over it again to make sure that I had not missed anything.  That document makes no reference to the same MAC address configured on two clusters.  It does refer to common files, like ringtone.xml, being served by the first server if it has that file.
Here the most relevant part:
Proxy TFTP polls all the clusters that it controls for the requested file, starting from its own database.
The cluster where the endpoint is configured returns the file.
The locale and ring list file requests do not contain a MAC address, so Proxy TFTP returns its own copies of these files.
However, because this is a cache, I assume the TFTP Proxy server caches a copy of the file (actually, if it does, how does it manage changes to the .cnf file?  Does it version check?)
