Zones in water duration

What is the advantage of being able to rearrange your zones in the Water Duration section of your daily schedule?

i rearranged my zones that soak to the top, this eliminated some of the hold soak time
so 2 and 6 soak, both on top, it may go 6,1,6,soak,6 where before it follows the order, so 1,6,soak, 6, soak, 6

now it would be slick to know it wanted to soak, and mixed the zone after other zones. say 6,1,6,3,6,4 vs 6,1,3,4,6,soak, 6
