You read it correctly. If your knees are healthy, your knee can safely travel slightly in front of your toe provided you warmup, progress systematically and allow for adequate recovery between workouts. This technique allows for a more balanced distribution of torque forces between your knee, hip, back, and ankle.
If your goal is to handle as much weight as possible, such as a powerlifter and you are less concerned about knee extension strength or quadriceps development, you can consider the powerlifting style squat which targets the glutes and hip adductors. With the powerlifting style squat, depending on your biomechanics, the knee may not need to travel as far forward as it does with the bodybuilding style squat.
Perhaps, in opposition from what you have been taught, with either form, keep your center of gravity between your forefoot and heel, distributed equally through the entire foot.
You can keep your feet parallel, if you prefer a relatively narrow stance. I would recommend your feet angle out a bit as shown in the diagram on that same page, particularly if you have a slightly wider stance. Just keep your knees orientated the same directions throughout the movement.
As you can see there are several options. Your form should ultimately reflect your personal training goals and individual biomechanics.
When experimenting with altered form, it is safest to begin with a relatively lighter weight on your first workout, then increase your resistance progressively each workout, until your workout weight is determined. This will permit adequate adaptation and will allow you to maintain better and more consistent form. Also see Adaptation Criteria.
