Preliminary context: how does an order placement work for a guest customer?

magento/magento2/blob/cf7df72/app/code/Magento/Checkout/Model/GuestPaymentInformationManagement.php#L73-L86


public function savePaymentInformationAndPlaceOrder(
    $cartId,
    $email,
    \Magento\Quote\Api\Data\PaymentInterface $paymentMethod,
    \Magento\Quote\Api\Data\AddressInterface $billingAddress = null
) {
    $this->savePaymentInformation($cartId, $email, $paymentMethod, $billingAddress);
    try {
        $orderId = $this->cartManagement->placeOrder($cartId);
    } catch (\Exception $e) {
        throw new CouldNotSaveException(__('Cannot place order'), $e);
    }
    return $orderId;
}

        $this->cartRepository->getActive($quoteIdMask->getQuoteId())->getBillingAddress()->setEmail($email);
