I brought up the pulsing in connection with a de-multiplexer, not to avoid the
resistor. If you just want to hook up a pair of LEDs to the RCX motor output, by
all means, use a proper resistor, and use forward/stop/reverse settings only.
Not using the proper resistor will fry the LED very quickly.

I would avoid exceeding the current rating on a LED, even for a fast pulse.
It's much easier to design a circuit with the proper current limiting
resistor, then to experiment with pulse widths. A wrong pulse width, with no
current limiting, will fry a LED instantly.
