AFAIR it many Moons ago in some "decending" exercises on the JP ( basic Jet) we taught power controls ROD and attitude controls airspeed, (Oscar Yankee's point) ...and that was the technique to be applied at medium level and was also the one to be used around the finals turn - e.g if you were low half way round finals you applied power to reduce ROD and raised the noise to control speed.
However once rolled out on finals the teaching was to point at the numbers and control speed with power. There was a bit of angst and discussion at times about teaching Blogs this apparent change in technique but at the end of the day as long as you realise pitch / power is interrelated, as we all know, then I guess we use whatever "method" works for us.
Frankly I reckon you are stuffed if you end up thinking too much about it - then again you should see/feel some of my landings on the 744
