As long as none of the underlyings trade at or below their respective barrier levels at any time during the lifetime of the product, your maximum return will be achieved by receiving the nominal value and the coupon.
The same return will be achieved after the barrier has been touched or breached if all the underlyings recover to close at or above their respective strike levels on the expiration date. In case of an early redemption, your annualized return will be higher because the coupon is paid before the maximum tenor of the note.
Therefore, the sooner the early redemption event occurs, the sooner you will achieve a higher annualized return.
