It creates sub-anchors within that anchor (with the process pid and a
connection id as part of the name), and the rules are inserted there.

The reason for that is that it's simpler to flush an entire (sub)anchor
than removing one specific (of potentially multiple) rules in just one
set.

Try pfctl -vs Anchors, it lists anchor and sub-anchors recursively. Then
pfctl -a ftpsesame/sub.anchor -s rules.
