BGP Confederation Problem?

I've configured a BGP confederation but ran into a problem.

I have R2 with the following BGP config.
router bgp 6502
 bgp confederation identifier 275
 bgp confederation peers 6505 6507
 network 150.5.2.0 mask 255.255.255.0
 neighbor 150.5.25.5 remote-as 6505
 neighbor 150.5.25.5 next-hop-self
 neighbor 150.5.27.7 remote-as 6507
 neighbor 150.5.27.7 next-hop-self
 neighbor 150.5.32.3 remote 341

When I look at the BGP table on neigh 150.5.32.3, it shows
the routes for the confederation with the AS_PATH containing
the internal (65xx) AS numbers.

   Network Next Hop Metric LocPrf Weight Path
*> 150.5.2.0/24 150.5.32.2 0 0 275 i
*> 150.5.3.0/24 0.0.0.0 0 32768 i
*> 150.5.5.0/24 150.5.32.2 0 275 6505 i
*> 150.5.7.0/24 150.5.32.2 0 275 6507 i

My impression was that the internal AS (65xx) would be dropped as
it was advertised to a EBGP peer.

Yes?
