Sveta, I remembered this and wondered about it, too, because I recalled that the collars were quite similar. It seems to be a case of them reissuing almost the same jacket with just slight differences. And I believe you are right - the collar placement is just fractionally different in the new jacket. And that tiny change makes it sit in a better place.
I always worry about that kind of neckline on a jacket but was surprise to find that I quite liked it when I tried it on. I did worry that it might fight with some types of shirt/ sweater and was pleased to see you model it with a turtleneck. I tried it with a button down (low contrast) and it seemed fine. I wasn't sure how it would look with a higher contrast button down, but possibly okay (based on your T-neck experiment). It would be good with a lower neckline, too, of course.
I also found that it was possible to fold the collar down in back and make a faux-lapel in front. I did this, just trying it out, and the sales associate says that you can "train" the leather to lay that way if you want to wear it more blazer-like.
The cut on these two looks almost identical. But did the first jacket have the shoulder and back seaming that the second has? I also think the addition of those zippered pockets lends the jacket something extra. They seemed to echo the collar's horizontal lines and that appealed to me somehow.
