An unauthorised transaction means that an account holders Paypal account was hacked and used without their consent by your ?buyer.
If Paypal check IP addresses etc and find in favour of the account holder then of course they are reimbursed.
However you would not lose out either as long as you met ALL the requirements of seller protection, so your best bet is to go and read up on it to make sure you were covered....sadly there is very little protection for digital goods sales.
