To have a foul, there must be illegal contact. With moving players that come into contact, you must determine if the contact is incidental or illegal contact, who is to blame if it is illegal, whether the contact resulted in an unfair advantage to the person who initiated the illegal contact, etc.
With no contact, they can move to their hearts content, on screens or anything else. They can move in such a way that if another player came into contact with them, they could be found to have committed a foul. But there is no illegal advantage gained by motion without contact.
