That would make it possible to write a virus that kills Pinephones... or installs tracking software or similar that is persistent even after flashing a new OS.The modem can be flashed without the USB_BOOT pin as well, the only difference is with the USB_BOOT pin it doesn't need a functioning firmware to flash the new one. From what I can gather the USB_BOOT pin makes the modem load a small shim from ROM capable of talking over USB and writing to flash but not much else.
