Yeah, that would be the "initiating" dichotomy that is shared between C and H subtypes. The more irrational ones, that aren't very interested in regulating the behavior or others and especially don't tolerate their behavior being regulated by others.
This was the only subtype of LSI I could relate to when I considered that type for myself. The first and last paragraphs imply the "contacting" dichotomy, which is the part that distinguishes between H and C. Being more contacting and proactive would make the transition from H to C.
