When renaming a user that is referenced on a same account S3 bucket policy as a principal I know that it automatically updates the user reference on the bucket policy to the new user-name per documentation. However, when the user from Account A is being used on another Account in a bucket policy, does it also automatically update it on the other account?

AWS Account A -> User A -> S3 Bucket with policy granting permissions to User A

AWS Account B -> S3 Bucket with policy granting permissions to User A

AWS Account A -> Renames User A to User A2

AWS Account A -> Bucket policy is updated to A2 (confirmed during testing)

AWS Account B -> Bucket with policy granting permissions to User A or User A2 now?

Yes, it will be changed to A2. I verified it using two accounts.
