^^it doesnt actually OVERWRITE data.. i just renders it unreadable. lets say u have 100 mbs left and u make a multisession cd then at the time of next burning session it will allow u to burn only upto 100 mbs but while reading this disk again, the previously burned data may get 'invisible' which is just a simpler way to say tht it renders it unreadable... if u r lucky, u may able to read from both sessions....
