I would consider this a valid assumption. I checked one of the ACS environments (version 4.9.2, updated from 4.5) that I know use multiple zones, and all of the templates that have IDs duplicated have crossZones==true.
We would need more information from this ACS that you are debugging to pin point the problem. How many templates that have crossZones==false are presenting this duplication problem? If it is a bug, I would expect everyone of them to have duplicated IDs. However, if this is the only thing they differ from other single zone templates, I would guess that these templates suffered from manual intervention in the database.
