Well, lets examine that passage from Acts 1:11 of which stated 'shall so come in like manner'
11 who also said, “Men of Galilee, why do you stand gazing up into heaven? This same Jesus, who was taken up from you into heaven, will so come in like manner
as you saw Him go into heaven.”
Strong's G5158 - tropos τρόπος (like manner) Strong's G3739 - hos ὅς (as)
Now one can takes this literally or figuratively, and one example would be that it is as figurative can be found in the use that Jesus referred to himself as a hen that would gather her chickens under her wings.
“O Jerusalem, Jerusalem, the one who kills the prophets and stones those who are sent to her! How often I wanted to gather your children together, as
a hen gathers her chicks under her wings, but you were not willing!
But more than this Jesus spoke of leaving to allow the Holy Spirit to come. It is in this 'manner' that I believe the ones speaking to the Disciples were using.
John 16:7 “Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you.”
John 16:16, 18-20
“A little while, and you will not see Me; and again a little while, and you will see Me, because I go to My Father.
18 I will not leave you orphans; I will come to you
19 “A little while longer and the world will see Me no more, but you will see Me. Because I live, you will live also. 20 At that day you will know that I am in My Father, and you in Me, and I in you
Looking closely at the above verses it becomes clear that Jesus is speaking of going away and coming back in the same context as sending the Holy Spirit. He says He is going away so that He can send the Holy Spirit, then He says He is coming back to them and that He and the Father will make their home with them. So from that context it appears that the particular “coming” that Jesus is talking about to the Disciples is the “coming” of the Holy Spirit.
And if one wanted to view the manner in which Jesus was taken that of a cloud it could also be said of the coming of the Holy Spirit coming as a mighty wind.
And suddenly there came a sound from heaven, as of a rushing mighty wind, and it filled the whole house where they were sitting
