You couldn't leave that permanently as the front pilot and rear lights are also powered from fuse B and they would then remain on.
No, it wasn't suggested to be a permanent fix, only an easy method to determine whether the "startus interruptus" fix is going to cure the non-starting. Once the starter button is pushed, just brush the free end of the cable (connected to the battery positive) across the back of fuse B is usually sufficient.
