Aaaaaaand now you're on ignore.
Like I said, you can wank eachother off the whole day for my part since I have no interest in those things. The fact of the matter is that I hardly come across any stand up specific discussion except a little bit for advanced muay thai guy where he compared kickboxing with surfing I believe.
At the start of round 2 (timestamp 3:41) you see the same thing, but now followed up with another action. He kicks with the backleg, after that his back leg stays in the front. Now he has switched stances. Then he kicks just as hard from a southpaw stance. After that he switches stances again and sweeps him off his feet. Try to do this with a wide stance, this is not possible as you are too much planted on your two feet. This is typical dutch kickboxing from back in the day. It's not just straightforward combination punching and finishing with a lowkick.
This is not possible by roundhouse kicks as they take too much time since you rotate too much. These are just hard kicks straight from the hips.
Take a look at how the guy gets knocked out starting from 4:06. The guy has a wide stance and is heavy on the front foot, and because of that lunged in way too much. From this position he starts his attack while being too much lunged in. Lucien is waiting for him to come in, while having his weight on his backfoot instead of frontfoot, which makes him harder to hit since he is relatively farther away with his head as opposed to his opponent.
See here the resemblances on stances by advanced muay thai guy and Xune-Ban. Now take a look how Lucien takes advantage on the head-first approach of Xune-Ban. This is one of the reasons this particular stable of fighters from that era were among the best standup fighters of the world.
True, there are more ways of doing things.just to let you know, during a fight, you cannot be in a "perfect" stance 24/7. Your hands are not always going to be up etc. The picture of myself your using your analogies on, the exact moment of that picture taken, is when I did a lunge fwd feint. My right shin was injured 1 week prior to this fight. Im more of a kick, knee, elbow kinda guy over punching, however I was working my boxing alot building up to this fight, and due to my shin being injured, I was forced to rely on my boxing heavily in this fight, which I did, as a result I ended up winning this fight due to my boxing.
To further my point, here are some pictures of saenchai fighting and training, and as you can see, his hands are not in "optimal" position. Please elaborate on how Saenchai needs to fix his technique. Point being, its not a perfect science.
