If you dont then anything that had been written to the logs before you switched it off will be lost. Additive basically means that the current content of the log file is not to be destroyed, which will always be what you want if you are trying to set things back the way that they were.

IMO, the ADDITIVE clause is optional because we sometime need to omit it.
If I always SET DEBUGOUT with the ADDITIVE clause, then I got no way to wipe whatever captured in the file and start all over again, unless I change to another output file (which I normally won't want to).

In fact, I don't have problem understanding how to use the SET command with respect to the ADDITIVE clause, my concern is to know how (or it is possible) I can programmatically determine whether or not the ADDITIVE clause is used in the last execution of the either of the above commands.
