Because all flags are reset at rest, and therefore have to be reset again after a test. A flag set indicates a certain condition, both with a system flag and a user flag, and a reset flag indicates the absence of that condition. With user flags, you determine the function for a flag, usually in programming. Therefore, there is no point in leaving a flag set if your program ends. Exceptions to this are system flags that you have already set while setting up your calculator. Therefore no FS?S instruction is present.
