If the user has placed "any" order previously (confirmed or pending, doesn't matter), then the "Your Orders" tab next to "Shopper Information" will start being displayed.
If the user has just registered (haven't placed any order yet) then the "Your Orders" tab will be invisible, because there is nothing to show there.
It is a Virtuemart feature. Virtuemart Core is responsible to hide and show those sections/tabs in the account management page. Our template just stylizes and make them look nicer, that's all. The functionality is still controlled by Virtuemart core files.
