[Question] PayPal, multiple email addresses!

Greeting!

I've a question about PayPal's multiple email addresses. I know that anyone can add up to 8 email addresses to a PayPal account. But, I just don't know what's the benefit of that.

Can anyone clear me about something? Suppose, I've registered with email address. Then if I add another email address as primary, then when somebody will pay me on my PayPal, in which address they should pay me?...
