My PC has 2 ip addresses (XXX and YYY) from different provider (A and B). I can't route packets with XXX source address on the link to B and viceversa i can't route packets YYY on the link to A (egress filtering). So i do policy routing to route packets with source address XXX on the link A and packets with source address YYY on the link B. Now if i can't choose which IP lfs binds to it will choose the first one configured on the NIC. If XXX is the first address lfs will bind to it and all my packets are routed on the link A but i want to use the link to B because is low latency. You can say: "swap the address order!" but i don't want to use the low latency link as default link for surfing web ecc.
