I looked at 220.127.116.11 and 18.104.22.168 and it seems to be a third version of SERP
“The data center remains the same,” Google tells us, “but different IP addresses can map to different data centers at different times due to how Google manages its traffic. Because of how Google employs custom load-balancing, there is not a single IP address that will always reach the Caffeine data center. For example, one IP address might still send half of its traffic to the Caffeine data center and half of its traffic to a different data center.”
it seems to me that sites which got more single-keyword links are preferred to sites which got more variety in anchor-texts on Caffeine.
