Sometimes the 7 core results may be padded out with local/news etc results, but there are only 7 actual page results.
I see no benefit from losing 3 results simply because there are sitelinks under the top result. Instinct yells "bug".
Maybe linked to the way they only serve 7 local results? Maybe not...
