Reflexive Access List

I have a question in regards to relexive access lists.
 I have the following config:

ip access-list extended inbound
 evaluate icmp_traffic
 evaluate tcp_traffic
 permit ospf any any
ip access-list extended outbound
 permit icmp any any reflect icmp_traffic
 permit tcp any any reflect tcp_traffic

-----
The access-list works fine but I originally had ospf
permit any any applied to both the inbound and
oubound. When I compared my configs to the solution,
the solutin only had ospf permit any any applied to
the inbound. I removed it and it still works. I then
removed it from the inbound and the neighbors dropped.
 Why is the ospf statement not needed on the outbound
side. It would have assumed that it would be blocked
unless specifically permited.
