The in that construction, in the context you mean, is generally (and in my view properly) used to link two declarative statements, each in a form that comprises a term in the syllogistic sense, where it refers to "each of the two concepts being compared or related in a proposition" (TFDO).
So you can say
A in that B.
where B is an illumination or explanation of A. Thus we can have
Abraham Lincoln was a statesman in that he acted in the best interests of his country.
or, a more complex example,
Hamlet is a religious drama in that it expresses the consequences of an unchecked evil that winds up polluting the main character and almost everything around him.
