Dot Tune Question

I have read and looked at the video of the Dot Tune method of tuning but there is one step I don't understand.  That is the one about using Live View or manual focus to initially achieve critical focus.   Why can't you just toggle the manual focus and activate AF to focus at various AF settings until you get the solid dot focus range of focus for each lens?
