In Chapter 3.5 S3 Bucket Policy, in the AWS Certified Security – Specialy 2020 course, inconsistent need for /* in the S3 ARN value in the AWS key

In Chapter 3.5 S3 Bucket Policy, you added / after the S3 ARN at minute 8:20, but at minute 14:26 the / wasn’t added to the S3 ARN and you were able to save the S3 Bucket Policy. Why in some cases /* is required and in others it doesn’t appear to be?
