We're/I'm talking barrel path. Yes, he starts his swing with the barrel above his rear shoulder (frames 7&8), but from there to contact (frames 9-12), his barrel is below his rear shoulder, and enters the zone from behind the plate...even though he makes contact with the ball well out in front of it.
With that, look at the young lady's barrel path, and see how her barrel comes over the top of her rear shoulder, and doesn't enter the zone until the middle of the plate or later...instead of her barrel going under her rear shoulder, and entering the much zone earlier like Trout's...and every other MLB hitter's swing(s).
LC only "launches"(not really, its an isolation) from over her shoulder there because her hands are moving fast compared to her body turn(her hands are much closer to game speed than her body turn). Hands still move on that path in game swing(down in front of arm pit)
At game speed her body turn moves her hands "forward" really fast so the barrel lays down really fast (lots of momentum). Under her shoulder just like everyone else.
I think theyre all trying(fighting momentum) to be as close to bisecting the shoulder as they can. All the "on top"/"down" thoughts get them closer.
