In fact, the ball travelled past the boundary ropes and was awarded a boundary in favour of the batsman.

Following the incident, Rahane suggested that some credit should also be given to the bowlers in such a scenario by declaring the ball dead.
“The rules are rules. Having said that, maybe the boundary could have not been counted. I told the umpire, at least don't declare it a boundary,” Rahane said at the post-match press conference.
“The T20 game is already heavily tilted in the favour of batsmen, and in such a situation, a ball can maybe be declared a dead ball. That was my conversation with the umpire,” he said.
Lynn went on to make 50 off 32 balls, while Sunil Narine hit a 47 as the duo shared 91 runs for the opening stand in 8.3 overs to help KKR reach the victory target of 140 with 6.1 overs to spare.
A similar incident happened on March 31 when RR faced Chennai Super Kings (CSK). MS Dhoni was on the strike and defended a delivery from Jofra Archer. The ball kissed the edge of his bat and went on to hit the stumps but the bails didn’t fall to give Dhoni a lifeline.
