I think you misunderstand the flow of traffic here. The data flow, initiated by requests coming from AWS us-east-1, was Cloudflare towards AWS, not the other way around. Cloudflare can easily control where and how their egress traffic gets to the destination (as long as there are multiple paths towards the target) as well as rate limit that traffic to sane levels.
