I don't know where Aushra explained the terminology, but the claims are as follows:

Information Based - Two statics or two dynamics. Functions of each partner's mental loop correspond to those of other partner's mental loop, and likewise for vital loop. More interchange of conscious, verbalizable information than subconscious impact. Termed "relations of repulsion" by Augusta.

Energy based - One static and one dynamic. Functions of one partner's mental loop correspond to functions of other partner's vital loop. More subconscious impact than exchange of verbalizable information. Termed "relations of attraction" by Augusta.
