Old and famous conductors usually conduct a bunch of very experienced or very talented musicians. They have more to worry about every musician getting to the right flow and tempo of the music, guiding everyone to be in-sync with what is happening. They have less to worry about a musicians's clarinette to be off pitch, sharp of flat, as most musicians of caliber have mastered this aspect.
This is why I think older conductors are busy keeping the whole puzzle in place, but mainly in regards to the overall placement of the notes and pace. Their undertanding of the structure of a piece, and their ability communicate it in waving that ''baton'' and get everyone to follow together is the skill and talet they most need to have.
They probably have to have less of the type of ear needed to discern one flat note from a trombone playing in the back, unlike what the high school teacher needs to have when teaching music to younger or less-experienced musicians who may not yet be able to produce a constant note with regularity and the right pitch.
Just my opinion, but based on some experience too....
