Communities User Names Uniqueness
Salesforce says the following:
"Customer Community, Customer Community Plus and Lightning External Apps licenses require unique usernames whithin the Salesforce Org. that a community belongs to."
"Partner Community licenses, Employee Community, Lightning External Apps Plus licenses require unique usernames across all Salesforce Orgs that the user belongs to."
Instead of having to memorize that, I would actually like to understand why (the underlying reason(s) for the uniqueness of the usernames being within the Org OR across all Orgs globally to which the user pertains.
Is there any logical reason that you can think of?

Lets assume you have communities setup based on different regions of the world where a customer could be a part of one of more communities so he could toggle around different communities with unique user name and still access the data and play around.
however lets assume you have created a community for a employee may be for HR portal he is assigned with a Salesforce license you might not want to have 2 different user names for same employees and allow to consume another license unless the org is rich enough to spend on it.
Hope that helped a bit would appreciate to seek a better reason if someone has more hands on working on differrent communities
