short answer, yeah... skip that step.
It is probably correct. Tripels are very simple, usually a Pils base, maybe a bit of aromatic, white wheat, or carapils, and some sugar. Usually a hop addition at the beginning of the boil, and maybe a little flavor addition.
If you care about keeping the color light, add half of the extract at the beginning, and half at the end (boil 10 - 15 mins), it will cut down on the number of carmelized sugars. Read up on late extract addition if you are curious.
