If you're multihoming it will increase your AS path length.There is no general correlation between AS path length and whether or not a network pays to exchange traffic.
That has nothing to do with what I was trying to say. When one mixes shorter/longer paths, you will generally see most of your traffic come in via the shorter path. It's like if I were to multihome with the local cable co (who has Level3 as an upstream) with a connection to Level3 myself. It's not likely that traffic inbound to me is going to choose the longer route unless the shorter one is down, and it's pointless as a backup because a regional outage affecting Level3 may kill the cable co's link to them as well. ~Seth
