It implied that the temporal effect of the final deceleration was analogous to how when you throw a ball up in the air and catch it, it only momentarily feels heavier than before you threw it. The twin only momentarily looks younger because the clock has to speed back up during the final deceleration and a naive calculation neglects this step.
