Quite right - it's the inclusion of the context that is more important, browsers without querySelectorAll or getElementsByName (special case for using the name attribute) would use getElementsByTagname('') in sizzle making it better to use jQuery('container').find('namesomeName') than just jQuery('namesomeName') - it might not be that important given browser support for.
