The source and destination IP addresses come of course from the packets. They have nothing to do with the interfaces - one can route any (sort of) packet with any source/destination IP addresses to whatever interface. Do you skip routers and think of end hosts only, where the destination/source IP address is that of the receiving/sending interface?
