How does Aurelion's passive work in-lore?

Strange question, but that's always something that I've thought of. If we were to see another, more combat oriented cinematic of Aurelion Sol, how would his passive work in-lore? From his current bio and color story, we can tell that he can forge stars at will of course and blast any of his enemies with a mass of bright, magical star energy, while his screaming ultimate and flying don't leave much to debate, but what about his passive? Is it just more of a visual thing in-lore? A constant halo of orbiting stars as seen in his login-screen? Or does he actually have a need to 'boop' his enemies when he can easily just throw an entire sun at 'em?

Just curious.
