Just to expand on what Vince already correctly stated, it is usually used in an environment where your AS is going through some changes, perhaps something like an acquisition. Maybe today you are AS 100 but you wish to change to become AS 200 but you have 10 BGP peerings with ISPs and other companies. Instead of coordinating so that everybody has to change all at the same time, you can implement dual-as which means they would be able to peer with AS 100 or AS 200 and do things on their schedule.
