Sanin, by losing his last game, will lose the opportunity to avoid an extra round or even two extra rounds in the losers' bracket. Does he need that?
De Luxe, by losing this game, will lose the opportunity to avoid an extra round in the winners' bracket. Does he need that?
If the transition round depends not on the place taken, but on the number of points scored, then it's a different matter.
But I didn't find anything like that in the regulations.
Only information that only the 1st places in the groups can advance to the upper bracket.
