"Closing" is sometimes called "Finalizing. When one writes multiple sessions to media, the disk may not be readable using software other than the original writing software until the disk has been "closed" or "finalized". After closing, no additional material can be written to the disk. So software which supports multiple session writing won't close the disk until you tell it to, so that the disk is still capable of taking additional data. If the person burning the disks never bothers to do that final step, then the disk won't be readable by software which only supports the standards.
