[c-nsp] router packets & outbound acl

I heard recently (during a cisco technical presentation) that packets sourced by the router itself, 
are not affected by an outbound acl defined on a router's interface; something that -at first- 
seemed a little bit strange to me.

I guess that seems normal in the following scenario:
1) the packet has the E0 ip as its source
2) the destination ip is routed through E0
3) you apply the outbound acl in E0

But what happens if the packet has its source on another interface from the one that the packet must 
pass in order to reach the destination?
