That would depend on what you actually did there :-)

I think the docs don't mention it, but in case "orient" is used, the 
area light's Y axis is effectively ignored.

The reason is probably because when you use "orient", it is no longer 
clearly defined in which directions the area light's axes point - only 
that the axes are re-oriented to be perpendicular to the direction of 
the light; so the result might get messy. And even if "orient" would be 
specified to try keep the Y axis "as vertically as possible" (like 
point_at does with the camera), it still wouldn't give you what you'd 
want for shadows above or below the light source.
