By doing that, the data section is always new 2. This is little bit advanced. You can duplicate your data section in the linker. One of them would change during the program run but another one would be static. When your program run (in assembly), always overwrite the data section with the static one. This would ensure the data section is always new. This is little advanced but would save the flash accessing time.
