If you'd checked the example you rely upon further down you'd have seen that in fact the individual Al-Qaeda groups are listed specifically in the State Department's listed of Foreign Terrorist Organizations. Now obviously I don't have the authority to say why that is, but it seems reasonable to presume that they are listed as separate organizations because they are, in fact, separate organizations.

Not necessarily. You don't want vague language in official documents, so you have to be specific, because you'd just shift the problem if you said "Al-Qaeda", since you now need an official list of Al-Qaeda-Subgroups.

If it would allow nesting, I'm pretty sure somebody would've already accidentally put Al-Qaeda under Ansar al-Sunna and cause a recursion error, blowing up DC.
