I think you're essentially right about this, but I will say it's a little bit overwhelming at first. I recently got on SRS for one of the servers, and it's pretty formal, like real ATC. I'm impressed with that level of immersion, but at the same time, I certainly didn't feel like I could start establishing any type of rapport with anyone, much less ask any questions. It looks like I might have a lot more exploring to do to of the various servers, squads, and comms options available then I originally wanted to, to be able to find a situation that provides the appropriate 'in' to really start learning the multiplayer environment.
