Traffic from the VPN server is processed in reverse order. The kernel does a routing table lookup again, finds the route towards the VPN server over the regular network interface, fills in your LAN IP address (because that's what its source address selection algorith spit out) as source address and routes it out of your LAN interface where it travels from router to router until it reaches the VPN server.
