Probably there is a difference. Actually inspector is an entity resource in Qt, only one is allowed to be exists. The opening is synchronous, normally based on the path:

if (isWebInspectorTest(url))
     layoutTestController()->showWebInspector();

Symptoms: it opens a new inspector, and close it right after the next timer event is called. Since there is only one exists at a time there is no inspector after the closing.

Besides, the closing is normally done just before the end of the test by:

function closeInspectorAndNotifyDone()
{
    if (window._watchDogTimer)
        clearTimeout(window._watchDogTimer);

    layoutTestController.closeWebInspector();
    setTimeout(function() {
        layoutTestController.notifyDone();
    }, 0);
}

And that is an asynchronous operation.
