Not necessarily. What it means is that if there is an issue with the system and you are forced to factory reset, only the information stored on the C:/OS drive will be affected. Every thing you have on the D:/Data Drive will not be touched by the procedure at all. So you should put your pictures, music and documents on there so that if there is ever an issue, you wont lose that information if you have to format and reinstall.
I for one have 5 Hard Drives split into 12 partitions. This way all of my data is stored apart from the OS. When I format and install various OS's my data is safe as it is never touched by anything that the OS install does.
