One reason often cited for payment processors not wanting adult companies is because of high level of chargebacks, but I don't understand this in the situation

One reason often cited for payment processors not wanting adult companies is because of high level of chargebacks, but I don't understand this in the situation at hand here: it is not that this company is going to stop accepting payments, it is that they are going to prevent sexual content and keep nudity, so it shouldn't change much the behavior expected around those chargebacks?
