Yes you can put it all in one domain if you'd like. Rather large domain IMHO, but is possible depending on how your topology is laid out. There is a finite limit of how many devices can be cascaded.
When they speak of region they're talking about MST region. With MST you need to have the configuration 100% the same or else it's considered a different region. MST scales more because of less processes running on the hardware.
