Only certain ITE models required reflashing because there is a memory inside that contain the EC firmware, in other architecture this is stored in a separate memory chip or in a main bios chip.
Most of asus models reflash it automatically

And what will lead me to flash these chips?i mean in which circumstances will be the machine in before i can decide to flash these chips
i have done this only 2 times once on acer with no display and on lenovo which i have changed kbc but would not come on.it is tricky and hard to do but I am sure you will be forced to do it.I hate to do this kind of repairs; perhaps getting old.
Main reason would be when you are replacing KBC with new one (because it's burned), and you will not always find pre-programmed chips for every model.
Until a few years ago the EC BIOS was either integrated in the main BIOS (single flash chip on the board) or had its own little flash next to it. Then they came up with the idea of integrating some flash memory inside the EC to do away with the external chip. That's why they need to be programmed.
Remember that by the time consequences of a short-sighted decision are experienced, the idiot who made the bad decision may have already been promoted or moved on to a better job at another company.
