No, this won't go infinite. A token isn't a card (even if it's physically represented by something that looks like a card), so a token leaving the graveyard doesn't trigger Quintorius' ability.

Just posting the rulings to support Rhadamanthus's answer:
MTG Comprehensive Rules:
- 111.1. Some effects put tokens onto the battlefield. A token is a marker used to represent any permanent that isn’t represented by a card.
- 111.6. A token is subject to anything that affects permanents in general or that affects the token’s card type or subtype. A token isn’t a card (even if represented by a card that has a Magic back or that came from a Magic booster pack).
