I've seen Knight-Princess pictures as being more representative of LIE-ESI Duality, but this description could relate to either of the two moderate Victim-Aggressor and Ni/Se couples.
I can also see the reasoning behind the LIE-ESI picture. The LIE as a visionary explorer, and the ESI as his constant support. Both aspects of the relationship (knight-princess and visionary-moralizer) are true.
The LSE-EII picture is funny (because it's true). The LSE in his khakis and the EII on tiptoes in her graceful slippers. She says "C'mon, big boy." He says "Huh?"
