Vauxhall Opel Corsa: Active emergency braking

Following on from similar discussions about driver assistance technology in cars, last year I bought a new Vauxhall Corsa and I am still trying to work out what the active emergency braking is supposed to do.

Looking in this car manual it says “Active emergency braking only works when the seat belts of the front passengers are fastened.”

Is it me or does that defy all logic? It will not work when I am alone in the car or only have rear seat passengers.

Is it only intended to supplement the protection of the front passenger air bag?

If I am alone in the car would I be safer driving around with the passenger seat belt fastened?

    The plural "passengers" could be referring to when it's a van and there is a double passenger seat with two passengers sitting side by side in the front as well as the driver. 

    I had a discussion about this a couple of weeks ago with a guy who worked for an insurance company, I said I didn't want to try it out. 

    The guy said when he worked for the insurance company he was often invited to test tracks by car manufacturers to try out new car technology and they had an inflatable wall to drive at. Despite knowing he was safe, it took him three attempts to reverse at high speed towards the inflatable wall before he did it without putting his foot on the brake. The system in that test car stopped it, the system in my car might only slow me down so the impact is not so hard hitting something head on.
