 The policy name is "Soft Landing..." and the motivations  are :

1- When we entered the exhaustion phase, We give chance to many to get IPv4 during the gradual transition  to  IPv6 and avoid that one or a few big ISPs justify the needs and take the /8 away

2- We have reserve for unforeseen future  which  i see may include upcoming IPv6-based provider and all the NAT-PT variants.......  and  who knows 

3- Promote IPv6 deployment(the policy add IP6 allocation requirements...)


Hope this helps
