My understanding of the "ups.start.auto" setting is that it only applies when an explicit shutdown command has not been given (and therefore would be overridden by one of the shutdown.* commands, if NUT is configured to manage the shutdown process).
That said, I'll defer to someone who knows the specifics of the Eaton hardware for information on how it should work. The UPS firmware has a lot of leeway in how the commands and settings are interpreted.
