I'm not familiar with Cisco rule sets, so please explain what the latter
rule does, exactly.

The rule 'pass out all keep state' in pf will let all outgoing packets
pass and keeps track of the connections, so incoming packets (replies)
of the those connections are passed automatically as well. Together with
a rule that blocks all incoming packets by default, this rule set would
allow only outgoing connections (but pass replies related to them back
in) and block incoming connections.
