I think the original wording was pretty good. There requirement for ASN is 
simply a unique routing policy. Eg. If you want to interconnect at an 
exchange / peering point, you need an ASN, but you're not technically 
"multi-homed" because you still only have one transit provider.

I'm a bit concerned about "ARIN assigned ASN." I'm not sure if it's possible, 
but what are the chances of an organisation applying to ARIN for address 
space but having an ASN assigned from elsewhere? Were there historical ASN 
assignments? Maybe ARIN can clarify if this is an issue or not.
