Well it depends what your phone is running out of the box, but the main reason is if you're phone happens to be on a pre-Knox (4.2.2) bootloader, its best to avoid updating to a newer one as once you have it you can't downgrade it. Or you will trip the Knox warranty when rooting/flashing recovery/custom ROMs.
So a check before updating/flashing anything is best, you can boot into download mode and check for a line that says 'knox 0x0'. If its there that means you have the Knox bootloader already, if not you're on the old one.
I'm still running the bootloader from I9505XXUBMGA firmware and so Im Knox free and can continue to flash custom ROMs (currently on custom stock based 4.4.2 rom) and revert back to full stock I9505XXUBMGA firmware if needed (so my device can be returned to out of the box state for warranty purposes). I only update the modem when needed, usually after there is a version or other significant change.
