Probably, but I suspect it would be induced by the vile taste. Not the presence of caffeine.
The press is notoriously horrible about summarizing medical studies and I would expect this to be the case here. I'd be interested to know if they filtered out other sources of caffeine, many people drink soda in quantities much larger than they would coffee. Also, since they were only studying short term effects how common the large consumption was. How many people drink four or more cups of coffee in an hour?
