Using S2Member - allowing checkout without PayPal account

Hi,
I understand that without a ERP or PayPal Pro account, there is no way to allow subscriptions to be processed without a PayPal account.
My question is, if I configure the PayPal button to be a "buy it now" one time charge that allows access for 1 year (this allows checkout without PayPal account) ---- what will happen at the end of that year if the customer wants to extend that year?
-- will they have to checkout through the system again & create a new user name?
-- can they check out again while logged in and S2Member will recognize that and extend their membership for another year?
How should this be handled?
Thanks for a fantastic plugin - if only all plugins were built and supported this well!
