They didn’t back him.
They backed Babar, and Babar exposed his inner bias by shifting him around to accommodate himself and Rizwan. They kept him out of the USA and India game, and paid heavily with Pakistan out.
They then were confused about which format to play him in. He tore the house down in ODI with T20 like performances, whilst Rizwan lead those clowns against Australia in T20s including himself as a leader.
He forced his way back into the T20 sides because even as an ODI batter, he was better than all Pakistani batters in T20 lol. Then Rizwan played the ultimate death move to the RizBar regime when he opened with Babar and lost the first T20i against SA, whilst Saim played the only T20 innings for Pakistan in that match.
Saim was forced into opening through all of Pakistan being outraged, and he played an innings that has ENDED RizBar opening in T20s forever!
