Unsure, but there are lots of variables there and there could be even more we don't know about not mentioned in the paragraph! Maybe more severe cases involved longer periods to help the patient calm down in the dark environment? I dunno! Just something smells fishy. You are right, could have also been training data leaking, just looks like there are multiple leaky elements here potentially!

Also, the study checked ASD participants were autistic by using structured interviews with psychologists against the DSM-5, but the TD participants were never assessed by psychologists, so if autism under-diagnosis is a thing, there could theoretically be false-negatives.
