Yep, that's all it takes. Google believes approve once, run many times. Just copy the code and off you go. Though consider using channels ( [google.com...] ) to track earnings from different sites.
That last point is important. It doesn't matter if the other site is low traffic, just as long as it is within Google's Terms of Service. The worse thing that could happen is that you get booted from AdSense because of a smaller secondary site that ran afoul of the TOS.
