But as far as "true symbol" goes, that was probably Miles messing with us. Right after he said it, Monty added that "it's nothing spectacular" and Miles admitted it was "arbitrarily added". They came up with the symbol, thought it looked cool, and simply added it to something he wears.

It's possible that with all the hype it caused, they might be planning to keep the symbol and make it important hence Jaune still wearing his hoodie. And it could work. I've seeing people creating theories already now that they know it's a bunny like Jaune being the hidden half-faunus or something among that train of thought.
