As I understand it, it's the result to a given search string that is cached. Sure, If I search for "44 little poney street", then the result itself is cached at Mullvad, and someone needs to search himself/herself for "44 little poney street" by entering precisely this search string to access the cached page. So I don't see a leak with caching... There are leaks anyway: the search term sent to Google, if someone compromises Mullvad, etc... But not one specific with caching and related to other users.
