Good Explaination from a linked in discussion http://lnkd.in/HnUtuY

Matty Vasquez • @Thuan Nguyen: When you run a search for users via the People Picker, Active Directory is queried (or any other provider you specify under the <PeoplePickerWildcards> tag in web.config, for instance: if you have users in a SQL database to provide FBA).

People Picker does not run under the Search Service, by default it uses the Application Pool ID to query AD, unless you run Kannan's STSADM command above to query a different Forest or use a different service account.

People Picker does not look up crawled User Profiles - this is used by the Search Service for People Search, which is something completely different.

So to reiterate - you do not need User Profiles and Synchronisation or the Search Service configured to use the People Picker - it queries Active Directory directly.
