No, it is fair in my view.
The person that shows the demo can for example choose to move and look and perform actions that are known to not cause performance trouble.
In a game a lot of unpredictable stuff can happen (for example, a bunch of people can cast a spell or drop a grenade at exactly same time). Or you may decide to quickly turn around causing a bunch of texture and geometry data to be loaded.
Game must take it into account and make sure the performance is acceptable with whatever input is allowed and lots of action around and not only when the guy walks slowly in a straight path and slowly pans around.
It doesn't mean it happens in this case but AFAIK it is fair to say that most engine demoes are put together to highlight strengths and hid weaknesses of the engine.
