Is AWS Q knowledge not up-to-date with AWS Documentation?

I was exploring which Resources are Supported by AWS Backup at this URL https://docs.aws.amazon.com/aws-backup/latest/devguide/whatisbackup.html#features-by-resource, when I asked AWS Q to explain features supported by AWS backup it said that Lifecycle to cold storage is only supported to AWS EFS, but in documentation it is different

and in documentation it is different

I wonder Is AWS Q knowledge is not up-to-date with AWS Documentation.
