He didn't mean it like that (or at least I think he didn't). Imagine it like person walking/running - When you are expect to walk at some pace (5GHz) you can do it proficiently for long time, considering you get your regular inputs and outputs taken care of (basic cooling, regular power drain), when you overclock - run, you need much more care to be able to run for a long time (stronger cooling, more power headroom, overclocking motherboard). What Intel in this demo did is strapped you behind the car and drove a 100 meters dash proclaiming - look he survived, he 'ran' that 100 meters run like a champ, it's possible to run this fast.
