why would i want multiple instances of the P1 sku in the same tenant?

Hi.  I'm reading as much as i can about licensing and came upon this statement at https://learn.microsoft.com/en-us/power-bi/enterprise/service-admin-premium-purchase .  Why would i ever have to buy another instance of the P1 SKU for my tenant?  

Now that you have a capacity, you can add more as your needs grow. You can use any combination of Premium capacity SKUs (P1 through P3) within your organization. The different SKUs provide different resource capabilities.

One for Dev environment and one for production environment, for example

thx Amine, as the question states, multiple P1s.  That would be multiple skus for production.  

Again can the community help explain a very basic concept here.  It could help a lot in deciphering the MS documentation.   Why would i want multiple production sku's?   What is the context or boundary of a sku's responsibilities  and how is it associated with just those responsibilities it is there for? 

Doesnt every company have just "one" production system?
