Most Confusing Match in Cricket History | McCullum Gets Angry? PSL 2018

This was a match between Karachi Kings v/s Lahore Qalandars in Pakistan Super League 2018. After watching this match I think the batsman should have been awarded 2 runs: * 1 run for no ball, * 1 run for completing the run on a no ball, but umpires did not. It was called out to be a dead ball, according to ICC rule section 2.5.4 under No Balls/Umpire Reviews. But my question is if the umpire had called the no ball the batsmen would have run. If it had been a dead ball wasn't the wrong batsman on strike? And if there is a rule that If the batsman is caught and umpire finds later it was a no-ball then the runs off bat won't be counted. If that rule applied here, then shouldn’t the batsman not be allowed to cross?
