Yes, but only partially.
At this point I'm no longer certain. I believe it started as a conglomeration of Billing Name and Shipping address. I'm certain the Title Bar said "Billing Information" since that surprised me. Anyway, I've managed to get accurate Shipping Information displayed. I'm just surprised I cannot find a way to also display Billing Information. I'm also unable to display the PayPal Express "Comment to Merchant" I thought it would be the "Custom" field in the ECO stuff from server behavior "Process Transaction with PayPal Express Checkout". But that displays nothing.
My recollection is correct. pp_checkout_success has the same issue. The header says "Billing Information" but it displays the Billing Name and the Shipping Address. Street2 is missing. I can fix it but remain confused as to the cause and I expected it would display both the Billing and Shipping Information. Code below:
<div class="eC_InfoContainer">
<p class="eC_OrderInfo"><?php echo ((isset($_SESSION["eCartCheckoutForm_firstname"]))?$_SESSION["eCartCheckoutForm_firstname"]:"") ?> <?php echo ((isset($_SESSION["eCartCheckoutForm_lastname"]))?$_SESSION["eCartCheckoutForm_lastname"]:"") ?><br />
<?php echo ((isset($_SESSION["eCartCheckoutForm_shipping_street1"]))?$_SESSION["eCartCheckoutForm_shipping_street1"]:"") ?><br />
<?php echo ((isset($_SESSION["eCartCheckoutForm_shipping_city"]))?$_SESSION["eCartCheckoutForm_shipping_city"]:"") ?>, <?php echo ((isset($_SESSION["eCartCheckoutForm_shipping_state_province"]))?$_SESSION["eCartCheckoutForm_shipping_state_province"]:"") ?> <?php echo ((isset($_SESSION["eCartCheckoutForm_shipping_postcode"]))?$_SESSION["eCartCheckoutForm_shipping_postcode"]:"") ?><br />
<?php echo ((isset($_SESSION["eCartCheckoutForm_shipping_country"]))?$_SESSION["eCartCheckoutForm_shipping_country"]:"") ?></p>
</div>
