Answer 1

Commerce pipeline is a typical implementation of CoR pattern and it applies very well to several commerce operations like order submit, pricing, etc, where an operation involve multiple discrete operations.
For instance following is a list of operation which happens during order submit:
1. Validate that order is ready to be submitted.
2. Clean up unused shipping group
3. Cleanup unused payment groups
4. Remove expired promotions
5. Authorize credit card
so on an so forth
Using pipeline makes all the logic decoupled and also makes customization easy. For instance if you want to add order approval for B2B customers you can add a processor for order approval.
