I guess it’s making a point of saying that if there’s an organised system in place, people will maintain their composure and leave without issue, even in an emergency.
It’s when there’s a lack of organisation and a bottleneck that means people start to get crushed, then all hell breaks loose when they truly panic.
Basically, the lack of organisation and a safe route out is what causes the panic where people stampede, not the emergency itself.
