Ignoring the writing flatline of that ending to the Yang short, it is established lore that characters cannot use their semblances if their aura's been depleted. That's why Pyrrha couldn't save herself and we don't see Ruby turn into petals at any point after hers breaks It's not entirely true that Yang's short is a contradiction to that point, as her semblance amounts to energy conversion, so if her energy was converted from aura beforehand, using it afterwards without aura could be compared to a mage using MP after their HP has depleted despite needing to sacrifice HP to restore MP.
