Why does a deny rule with sub_rule return true when filter doesn't match?

Hello,
maybe it's something that I don't quite grasp around casbin config, but shouldn't this return false ? Since we have a deny rule ?

Ok so I've understood my mistake. The sub_rule acts as a filter to whom this rule will be applied to. In my case, age 10 falls out of the filter, so no rules are applied, so it returns true

yeah did that, but the explanation fell very short of the actual answer
