AdSense search update?

See two boxes of ads in results

Now the "site search" results page shows adSense ads at both the top and the bottom of the result page (above the "next page" links). When did this happen?

They've both been there from when the service was launched.

Thanks.

What it was was this: I just hadn't seen it before, because the searches I did only came back with 4 or fewer matches (often no matches). You only see the bottom ones if there are more than 4 - in other words, the bottom catches the "overflow" from the top.
