Nope, it all happened during that generation. Look at the original literal question.
3 And when he is sitting on the mount of the Olives, the disciples came near to him by himself, saying, `Tell us, when shall these be? and what [is] the sign of thy presence, and of the full end of the age?'
They wanted signs of when the temple would be destroyed, Christ's presence and the end of their age. Of course, Christ's presence returned to destroy the disbelieving Jews and the temple. This presence return was exactly the same as when God's presence came down 4 times in the 6th century BC to destroy four wicked places.
