I know that in normal conditions it's poor maintenance that kills most chains, but you have to take in account that the load on drivetrain is highest when you're doing something odd, like sprinting uphill on high gear. If somebody has enough power to do it then such loads, even in short time, could put much bigger stress on components than few months of casual riding. In fact it could be totally different kind of stress, more like short bursts of very high mechanical pressure instead of prolonged linear stretching over time. And given that even best components could have subpar batches, IMO it's totally possible to happen.
