To me, relaxing these rules is less about lying - although is easy, but it is to do with flexibility.
I understand the routing policy wont be different that an upstream without being multi-homed, but it does curtail the convenience of being able to add these things easily.
Lets say I was a company with a /23 and upstream into Telstra Only. If I had my own ASN and was announcing to Telstra, then at any time I could add another ISP, IXP, direct peering without having to go apply for an ASN, reconfigure my network to bring the announcement in-house, etc.
I also might want to maintain a single provider, but be able to migrate easily to another provider without having to rely on the providers to do the "right thing" while changing announcements between them.
I think this policy has VERY valid applications for many smaller entities to be able to have an ASN without having to be multi-homed either initially, or maintain that multi-homing.
As Randy used to say - Why do you have the right to tell me how to manage my network? If I want to be multi-homed, or change my mind and not be, it is none of your damn business.
I think this policy change reflects the changing way for businesses to get online since APNIC has run out of IP's, and are often charging significant amounts of money - so people are going to APNIC directly - which they are entitled to do. And being flexible and being able to change their circumstances is a more common thing nowadays.
If you want, suggest charging for ASN's... but don't tell networks how they should be connected at any time.
Btw... I am happy for this to apply ONLY to ASN4 and not ASN2.
