It seems to me that this passage is more likely a reference to post resurrection events.
The Son of Man ascended immediately following His resurrection:
Now Mary stood outside the tomb crying. As she wept, she bent over to look into the tomb
12and saw two angels in white, seated where Jesus’ body had been, one at the head and the other at the foot.
They asked her, “Woman, why are you crying?”
“They have taken my Lord away,” she said, “and I don’t know where they have put him.”
14At this, she turned around and saw Jesus standing there, but she did not realize that it was Jesus.
He asked her, “Woman, why are you crying? Who is it you are looking for?”
Thinking he was the gardener, she said, “Sir, if you have carried him away, tell me where you have put him, and I will get him.”
Jesus said to her, “Mary.”
She turned toward him and cried out in Aramaic, “Rabboni!” (which means “Teacher”).
Jesus said, “Do not hold on to me, for I have not yet ascended to the Father. Go instead to my brothers and tell them, ‘I am ascending to my Father and your Father, to my God and your God.’ ”
Mary Magdalene went to the disciples with the news: “I have seen the Lord!” And she told them that he had said these things to her. John 20
Then He descends again:
Now that same day two of them were going to a village called Emmaus, about seven miles from Jerusalem. They were talking with each other about everything that had happened. As they talked and discussed these things with each other, Jesus himself came up and walked along with them; but they were kept from recognizing him. Luke 24
Then He ascends once more:
When he had led them out to the vicinity of Bethany, he lifted up his hands and blessed them. While he was blessing them, he left them and was taken up into heaven. Then they worshiped him and returned to Jerusalem with great joy. And they stayed continually at the temple, praising God. Luke 24
