1. The `multishipping/checkout/overview` page:

The «Place Order» button sends request to multishipping/checkout/overviewPost:

2. Magento\Multishipping\Controller\Checkout\OverviewPost::execute()

magento/magento2/blob/2.2.0-rc2.2/app/code/Magento/Multishipping/Controller/Checkout/OverviewPost.php#L64-L146


/**

        $paymentInstance = $this->_getCheckout()->getQuote()->getPayment();
        if (isset($payment['cc_number'])) {
            $paymentInstance->setCcNumber($payment['cc_number']);
        }
        if (isset($payment['cc_cid'])) {

        $this->_getState()->setCompleteStep(State::STEP_OVERVIEW);
        $this->_getCheckout()->getCheckoutSession()->clearQuote();
        $this->_getCheckout()->getCheckoutSession()->setDisplaySuccess(true);
        $this->_redirect('*/*/success');
    } catch (PaymentException $e) {
        $message = $e->getMessage();
        if (!empty($message)) {
            $this->messageManager->addError($message);
        }
        $this->_redirect('*/*/billing');
    } catch (\Magento\Checkout\Exception $e) {
        $this->_objectManager->get(
            \Magento\Checkout\Helper\Data::class
        )->sendPaymentFailedEmail(
            $this->_getCheckout()->getQuote(),
            $e->getMessage(),
            'multi-shipping'
        );
        $this->_getCheckout()->getCheckoutSession()->clearQuote();
        $this->messageManager->addError($e->getMessage());
        $this->_redirect('*/cart');
    } catch (\Magento\Framework\Exception\LocalizedException $e) {
        $this->_objectManager->get(
            \Magento\Checkout\Helper\Data::class
        )->sendPaymentFailedEmail(

    } catch (\Exception $e) {
        $this->logger->critical($e);
        try {

        }
        $this->messageManager->addError(__('Order place error'));
        $this->_redirect('*/*/billing');
    }

Note that Magento 2 creates separate orders for each shipping address:
