The "focus at longest focal length and zoom out" technique comes from 
motion picture shooting, where it isn't usually any more precise than 
with still photography, but is the only practical way to work when 
you're zooming *during* during a shot... Unless you have the budget to 
hire a separate crew member as focus puller, and I've never worked in 
film environments that were that classy! ;-)
