Lebedev: I contradict myself

The other day, I accidentally decided to find something in the search for the Art. Lebedev Studio ... and I accidentally discovered an interesting inconsistency on the site. I remember in one of the paragraphs of Lebedev Lebedev wrote that it was wrong to write a double copyright combination
(for example, Copyright © MyCorporation 2000—2008), because this oil is oil, it turns out
"Copyright Copyright ..." But on the website of his studio, and not on any archival page, but on the page where search results are returned, you can find this very oil-and-oil one.

www.artlebedev.ru = © Art. Lebedev Studio 1995—2007

www.artlebedev.ru/search/search.html?text=%F5%E0%E1%F0%E0%F5%E0%E1%F0 = Copyright © 1995—2007 Art. Lebedev Studio

Enough funny mismatch. Dear habrareyudi! What do you think about copyright arrangement? Waiting for comments.
