Absent filtering, AS2 would send all three routes to it's BGP peers, but your NO EXPORT community will cause the two /17s to be filtered, so only the /16 will make it beyond AS2.
Correct me if I'm wrong, but isn't there a synchronization issue here as well? E.g.: AS2 is transit provider, probably has bgp synchronization on (default), and will only propagate routes to other AS's that have made it into their IGP. The question then is: have all 3 routes made it into AS2's IGP successfully? Only if the answer is yes, will it actually propagate that /16.
