Paid membership Pro and tow checkout

My question is, if the paid membership pro plugin works automatically with the 2Checkout payment gateway , that is, if the charges are made automatically as paypal and when he pay, he will have automatic access to the Subscription and the course. And what happens when the subscription period ends , ( the student is unsuscribe form the course? , loses its avanze ? ) Finally, when the user buys the subscription again, he/her return to the point where it left off.
