I think that Semblance was refering to each persons apptitude of sorts. Each person has something that they can do with their aura that others can't, based on that person. Since a persons aura is said to come from their very soul, then the powers would vary drastically in different people. Some people may have similar powers, such as Blake and Ruby (and possibly Adam) having an affinity for speed, where others are completely different like Pyrrha's magnets.
