Because the windows were made larger by bringing the lower edge of the trim downward, that now interferes somewhat with the style lines that came across the front fender and below the leading edge at the front, as well as from the rear fender and forward below the rear windows. The absence of those styling cues gives an optical illusion that makes it seem the 'shoulders' are less pronounced. They are still fully there, it's just that the flourish of the styling pen is lost in translation.
