It was announced 3 games before and they had Chemik,Modena and Baku.
They lost for Chemik 3-2, but Chemik was leading 2-1. Was easy for Conegliano tie 2-2 once they had no pressure at all.
They beat Modena 3-2, tie break 18-16. I doubt they would have won if they won if they did not know they were hosting, They played with no pressure at all.
And even against Baku, Baku was already out and had 0 motivation to win or even to put on a better fight.
I doubt that. It was announced 1 or 2 games before the end of the pool stage and their opponents were Chemik and Modena.
