Here is my guess
Twitty works for Amsouth....he is NOT the President of Amsouth.
Amsouth has some reason to register as a RI Corp in order to do business there......it is (probably best called Amsouth-RI) a 1000 share corp with zero value to the shares, and in fact Amsouth has no office in RI.....CT Corp is their resident agent for RI govt purposes. this thing is fairly described as Amsouth getting a license to sell insurance and investments in RI.....the "Presidency" of Twitty is limited to that RI nearly-non-entity. Meanwhile, back in Alabama, Twitty is an employee of Amsouth, not an officer or director.
Not surpsisingly, Amsouth is handling the Natalee Trust:

Was an interesting dvelopment in a way. The theory on SM was that it would make sense that Natalee was kidnapped. But I see what you mean as to Twitty's relationship would be minor in the whole scheme of things.
