The branch logic allows you to create multiple paths when the yes/no logic won't work. This will allow you to create multiple paths depending on the results from the previous step.
You can check the value from the previous step and depending on the data you can create multiple pathways.
For Example: If you are an eCommerce store that needs to forward the orders to various Suppliers.
When someone creates an Order, you will loop through the product, and based on the product or product category you can send notifications to various suppliers. You can name the branches whatever you like.
