Leg length discrepancy and stance width : AdvancedFitness

Some coach told me that the wider your stance is on squats and deadlifts the less pronounced the difference in length between the legs is, to what extent is this true? So for example if someone had a 2cm difference between the length of their legs, about how wide would their stance have to be in order for their hips to be as laterally even as a person with 1cm of difference that has a shoulder width stance.
