Purely FWIW, my rule-of-thumb (which has one or two glaring exceptions) is that, for most people, Aura is passive and Semblance is active. Whether it is consciously so and always so is a different matter.

In Jaune's case, my gut feeling is that his Semblance is a reactive force-return field whilst his aura causes the healing effect we see in during The Emerald Forest.
