when the emitter is on ground, the base voltage (when on) is nearly
independent from the diode characteristics, and therefore it's a bit easier
to calculate the correct base resistor. if you leave enough margin, it
probably doesn't matter much, but you have better control and the necessary
margin is smaller.
