Late extract additions are a method for extract brewers who do not (or cannot) boil the full amount of wort. Boiling highly concentrated wort can cause the extract to carmelize, which darkens the beer and affects the flavor. Some also believe you get poor hop utilization, meaning you'd need more hops to reach the recipe's appropriate number of IBUs.
I use the late addition method all the time. It's debateable whether hop utilization improves, but there's no question that you get lighter beer.
The way I brew is I add 20% of the extract at the beginning of the boil, then the remaining amount when there's 20 minutes left. The pic below is the most recent beer I brewed using this method with DME. As you can see you can get very light colored beer.
