Saving - and now seemingly publishing - search queries is saving and publishing PII.
http://donttrack.us directly acknowledges that search queries can be used to personally identify individuals.
I therefore understood from the later statement on that site, "[ddg doesn't] store any personal information at all", that this would include search queries: ddg almost literally advertises itself on the fact that it doesn't save search queries. (According to the small print, I understood this wrong.)
It would be a shame if your explanation was the correct one.
