Tested a few scenarios (not sure exactly which one) but in my testing caused the root of the VM melded to its template when using local storage on KVM;

• VM migration (with local storage) from one host to another
• VM's root disk volume take snapshot & revert to the volume snapshot
• VM's instance snapshot first with disk & revert; next VM snapshot with memory & revert

Expected that VM's root disk in case of root disk still uses the template as backing file.
