In your shoes I'd be wanting the same clarity believe me! It's almost like they've cleverly worded it so that they can say it's got an Eco mode when all it is is a bar to tell you when you're riding "optimally" for fuel efficiency. Which if it is, isn't a "mode" and more a guide so I'd be a little unhappy they had worded it as such. Hopefully the dealer will be able to clear up the mess for you soon
