Answer 1

What is the reason behind sort-limit-sort-limit approach?

Can't you just do

$cursor = $collection ->find($query)
            ->sort(array('user_id'=>-1))
            ->limit(1);

EDIT: Also, only the last sort applied to the cursor has an effect. (This line is present in pymongo docs here, which makes sense.)
