Ah, now I understand how you got there from here. I didn't notice that little detour road, but now I follow. Let me respond to that; I don't actually see a correlation between Jesus' ascension and the Lord coming with clouds under his feet, or even those of us going to meet those who are in the clouds.
When Jesus ascended, it seems pretty clear that this was a literal event, as it says "a cloud hid him from their view" (Acts 1:9), and that would make sense if he was literally ascending into the sky, as it was told. However, when we're talking about "those in the clouds", that's likely not a literal description because clouds are not always in the sky, so would "those in the clouds" only appear in certain parts of the world? What if my part of the world is under a clear blue sky that day? Am I out of luck? No, it just doesn't make sense that way, but a symbolic understanding here, of power and glory, always applies, so that makes a lot more sense. Also when it says things like "Behold, Yahweh rides on a swift cloud, and comes to Egypt" or "clouds are the dust beneath His feet" or "It will be a day of clouds" or "upon the cloud one sitting like to the Son of man", these are clearly not literal because even Jesus does not sit on a cloud, or have clouds follow him under his feet, because a cloud does not have a well defined surface, except in cartoons, that you can define where the top of the cloud is in order to sit on it. A cloud is just a mist. It may look tangible from a distance, but when you get closer, you realize that you can't define its edges. No, in these symbolic passages, clouds symbolize glory and power. That much is clear.
