The reason is quite simple, many games (even some old ones) receive an update time to time.
I would suggest, to get a backup drive (HDD / SSD) or even better a NAS (x2 HDD). Large HDD are really cheap nowdays.
If you don't have the lastest version of all your games if GOG closes; some of your backup on dvd-r will be outdated. (sure that shouldn't be a problem if your collection is small, but if it's quite large, i won't do that)
In other hands, i think GOG is reliable, so i don't think you really need to backup on dvd-r but it's your choice.
