I wear different shoes with my commuter depending on the task and distance... different shoes have different thickness soles... requiring adjustment.
My MTB is ridden on and off road... off road I tend to lower the seat for better weight shifting, on road I want it fast, thus higher.
Not everyone does this, but there are two reasons for you. My road bike has a fixed bolt... I never change it.
