It means exactly that. This is in the spirit of the old free version of Mailinator. Use a randomly generated string as the local part of the address to prevent others from guessing and looking that that inbox.

Mailinator of course still works this way too. It has private domains, but it still fully supports public,free,disposable addresses @mailinator.com.

Just enter any inbox you want at the top of the homepage.
