Blue bike has an older bend style bar with a newer type brake lever.

the bar in #2 has a shorter ramp. which are an adaptation to the lever bodies getting longer
and the angle they meet the bar, note how the top example is rather a continuation of the bar.

when the shifters were elsewhere, longer ramp, then the hand grasps that portion
sliding forward to brake. whose hood portion was shorter..

but with the brifters staying on the lever hood is common,
so the bar bend brings it back towards you a bit.
