The new feature (and underlying HAL) both explicitly allow the radio to ignore restrictions on network types when making emergency calls, so this is not the distinction being drawn. There is also nothing the OS can do to shut down 2G in most cases; the best it can do is ask nicely that the baseband does not use it. So the "shut it all down" theory is also not correct.
