I think we saw Hasbro, at the time of the OTC line, mimicing (again) 21st's line, to acheive the versatility needed for the two iconic poses (since super articulation was still a rarity)... At the time 21st Cent. Toys included two sets of arms only. Hasbro was JUST starting to adopt the new methods for manufacturing figures so that they would actually be capable of doing the removable limb thing, easily, at that time. It was still actually fairly uncommon in the line to have a torso even capable of that.
Now flash forward the latter waves of the military line, and they took their idea to a new level by adding legs for figures that benefited from prone poses due to their accessories or intent (artillery, MG teams, etc.), and a new lower body design overall with the latter couple waves produced. And again Hasbro uses the same idea/designs to great extent by knocking out Leia's probably most iconic "lounging" pose which is pretty tough to acheive with articulation, but still giving fans that extra articulated set of legs so they make that "definitive" Leia (3rd time's the charm I guess). It's a first figure and I'm curious if it'll lead to any others. Luke didn't really give way to others.
I love it, and to me it's miles superior to the Dagobah Luke. Luke looked good but was ultimately still a statue (definitely a figure I'd like to see delivered with super articulation) any way you sliced it. Leia delivers both styles. For me this is what I always asked for from the 2002-ish era, with the extreme posing... Having both "styles" makes me actually appreciate my old 2002 Jedi a little bit more than I did in 2002. Now that I know I've got a suitable Luminara Unduli for all seasons, for instance, my 2002 figure doesn't look quite so bad... Almost a little artistic looking.
On the likeness, I liked it too, actually.

The POTJ Deluxe is nice, but I think this looks superior to me... I'm probably more forgiving on human likeness issues though, so I tend to overlook them if they're not too bad. I liked VTSC Luke Bespin for instance. Didn't care for the deco, but I thought the sculpt was there and just needed a better skin tone (like Ceremony Luke as well).
