Sorry, the poster at AvHerald got it wrong. The audio recording has ground controller instructing MSR 986 to turn onto 22R, taxi down and exit at Juliet:
"EgyptAir 986 heavy, I need you to go right on runway 22R and hold short off Juliet"...
"EgyptAir 986 heavy, right on Juliet, taxi right on Bravo."...
"And EgyptAir 986 heavy, I need you to go right on Bravo and hold short off Golf."...
"EgyptAir 986 heavy, I need you to join Bravo at Hotel, please."...
According to this, MSR986 could not have entered 22R at Juliet. The last instruction also seems to indicate, that MSR986 messed up again and exited the rwy turning right onto Alpha.
