Thank you for that explanation. I'm pretty sure I understood what the beta server was for the first few times I was invited. What I found odd was having announced beta content for the current expansion reachable the usual way ie hailing an npc in pok and at the same time having unannounced content for a future expansion that is only reachable with the assistance of a guide or dev. I assume at some point in the future SOE will announce open beta for the next expansion and the new zones will be reachable by hailing the same npc in pok. I guess it's a result of staggered development overlapping with future development.
