Answering your question: the sun is, to the viewer, behind the clouds in the foreground. Beyond the sun, but certainly not as high as the sun, there are more clouds that the sun travels in front of. The sun appears to be nestled in the clouds because of perspective of the viewer. But in no way could the clouds that are "behind" the sun even appear that way if earth is a globe.
You haven’t answered the question. This has nothing to do with the viewer from the perspective of the video.
Both of those cloud layers are over the Earth and not very distant, nor very far apart. In fact, they must be overhead for people beneath them. Therefore, if the Sun were between them, as you claim it is, those underneath those clouds would have to see the Sun passing overhead with those layers of cloud to either side:
Of course, you will never see this, ever. You could get into your car and drive to be underneath those clouds, but guess what? The Sun will be BEYOND them - just as you can’t get “underneath” the Sun by driving towards it, as one would be be able to do if it were no more horizontally distant than some clouds!
The fact that you can’t grasp this just boggles the mind.
