so beings that beta is planned for almost a year from now and they are still adding key feature that makes this alpha, pretty easy to understand.

although the definiton says "is often performed only by users within the organization" it is not defined by that because it says "is often" not "all the time"
Syntaxlies, you forgot "Open Beta" which I think is where FFXIV is in.... A paid open beta though

Open betas are from a larger group to the general public and anyone interested. The testers report any bugs that they find, and sometimes suggest additional features they think should be available in the final version.
