James,

So this provider would select the path with the longer AS_PATH length and would advertise this one to its peers (if 
any). I believe then its for the others to decide if they want to take this route or not.

Is my understanding correct?

Thanks,

 Would it ever make sense for a provider to chose a longer AS PATH length BGP route against a shorter AS PATH length 
route?
 
 
 Yes many do - Prefer your customer routes via customer interfaces, over
 transit and peering interfaces.
 
 Higher LP over cust interfaces = more bits = more revenue. There is nothing
 wrong with this IMO, considering many of them who do this, also provide
 a community for customers to override this behaviour.
