Wash walls from bottom up or top down??

For decades I've read that when washing walls, start at the bottom,
and I've never understood it.

Now I have to wash a wall, and I need someone to explain it to me, to
convince me that that is the proper way.

Seems to me if you start at the bottom and get it clean, there will be
dirt running down the wall onto the clean part as soon as I get the
part above it wet. *And I'll have to clean the bottom parts over and
over again.

Helpful advice appreciated.

I never like to do anything more than once. (With respect to cleaning
something.) Cleaning from the top down means that I don't have to go
back over an area that I have already cleaned because of dirty water /
cleaning solution running down on an already clean area. If I am
doing a wall, the last thing I want to have to do is get down off my
ladder to reclean an area that I have already done. I don't know
where you read the clean from the bottom up but it goes against
everything I have ever heard, seen, or logically concieved.
