You certainly can add DME if your OG is off- lots of people have had to do that on their first view AG beers.
Some people probably do "adhere" to that technique, but think of it as saying you can
sparge up to .5 gallon per pound of grain, not "have to
" and I think you'll find it easier to think about. Maybe in pro breweries where they are trying to extract every bit of the grain's potential out of it, when costs are concerned, that makes sense to maximum your efficiency. But spending another $10 for propane to make up for one pound of grain isn't efficient for homebrewers.
