Yup there is some confusion about this. You are really just required to provide a 20a circuit for the "laundry". There is no restriction about how many receptacles can be on that circuit or what you can plug into as long as it is in the laundry.When I see a single 20 behind the washer location I understand someone has misunderstood where we are supposed to be going with this. They want you to be able to run the washer and the iron at the same time.
Kids there used to be this thing called an iron ...
