Continuous Delivery with AWS: Confusion between Staging and Prod

Context
Course: GitHub Actions: Continuous Delivery with AWS

Expected behavior
The staging and production deployment should be deployed to two separate resources that are at parity.

Actual behavior
Step 7: Test the staging action triggers staging deployment, and Step 11: Merge the production workflow triggers production deployment, and both deploy to the same endpoint.
To make things more confusing, the output has mixed Staging and Prod keywords
