How to understand ConsumeConcurrentlyStatus.RECONSUME_LATER

My consume code is follows
`
public class HrConsumeListener implements MessageListenerConcurrently {
@Override
public ConsumeConcurrentlyStatus consumeMessage(List list, ConsumeConcurrentlyContext consumeConcurrentlyContext) {
try {
list.forEach(messageExt -> {
System.out.println(messageExt);
});
int i = 1/0;
return ConsumeConcurrentlyStatus.CONSUME_SUCCESS;
}catch (Exception e){
System.out.println("消费失败，offset不移动");
return ConsumeConcurrentlyStatus.RECONSUME_LATER;
}
}
}
`
When consum fails, consumOffset still moves，I don't think it should move，but why?
