For some muscles I would say yes, and other no. Back for instance, needs to be worked form a variety of angles. That is what it is designed to do: it can pull down, up, back, or combinations of both. This is b/c the basis for the back is the shoulder joint ( a ball and socket joint). A BASJ delivers the greatest ROM of all the joints, so for full development you must incorporate different angles of pull in the workout.
The biceps though are much simpler. They cross a hinge joint whose only job is elbow flexion. That is what the bicep does; produce elbow flexion (and assist in supination). So aside for changing hand position (pronated, supinated, etc.) most bicep movemnts are redundant in typical bicep routines. For example, lets look at dumbell and barbell curls. They both produce elbow flexion. Your bicep doesn't know if it is curling a 50 lb. dumbell or taking 1/2 the load on a 100 lb. barbell (still 50 lbs. in each arm). It just cares about the resistance put on it.
