IANADS and it took a reread to parse it. It's a bit weird but it draws attention to the point. For others interested, basically at 95% confidence level, there's a 5% chance due to random events. At 99%, the randomness is limited to 1%, a 5X improvement, i.e. a huge 500% improvement not a tiny 4% improvement.
