Yep. It's what the RAF teach and is I believe more and more relevant the larger the aircraft. It hinges on having an aiming point (so a bit iffy into a grass field with no markings) and to a degree on achieving a set point on the approach (the 400 or 500 ft point). If you are low or high on the approach to start with then you can't use point and power to correct except by changing the aiming point which rather negates aiming at the threshold, so you have to use power to control RoD etc. If however you are set up nicely at the 400' point it works very well.
