The 10% is a catch all for the loopholes in the law that allow coalitions to fish up or eliminate a candidate. By displacing (a) pluri-elected candidate(s) around the national checkerboard any number of scenarios can be created in order to recuperate a loser or borderline case. So once the tally is in, each coalition pulls out their shopping lists of who they really want in and don't want in other than those who have already been assured a seat. As in the example above, imagine that the coalition wants to recover number 17 or conversely prevent number 16 from being assigned a seat. By jostling the pluri-elected around from one region to another either scenario is possible. It is actually more than ten percent in the House but again it depends entirely on party bargaining within each coalition. Popular mandate has no role in determining who will be nominated MP.
