This is the spot in question, right? From the looks of it, you can either lay blame on Ziggler, or chalk it up to miscommunication, which either both or neither person should be blamed for. Certainly can't blame Sin Cara alone, though.
Notice that they both attempt to put their foot on the top rope at the same time, in the same area, just before the fall. I can't tell if that's what caused Ziggler to slip of if he legit just missed the rope. He shouldn't have had a problem placing his foot directly next to Sin Cara's on the rope though, had he taken his time to let Cara put his foot up first.
You can either say it was an accident due to miscommunication (one of them should have told the other whose feet were going on the top rope first, instead of them trying to go on top simultaneously). Or you can blame Ziggler for simply not placing his foot properly and slipping....or for trying to put his feet up first. The few times I saw Sin Cara do that move, I notice that his feet always went on the top rope first before the opponent's.
Sorry about the paragraphs.....I just like to analyze a good botch every now and then
