No, there is no change or twist in the match. Although Srilanka have lost 2 quick wickets but when you look at the bigger picture it is not 51-2 , it is in fact 200-2 (if you add the lead in the score too). No matter how many runs Srilanka makes in the 2nd innings, it will still be a giant total for Pakistan to chase. The big first-innings lead gives Sri Lanka a lot of freedom and advantage in this match and i don't see they can lose from here.
