Well spotted on the video edit, if that is true.It cuts between one shot and a closer one where the second camera would be in the first camera's shot. The two shots couldn't have been done in one take. It's just a music video with the artist lip/hand/foot syncing to his studio recording. That's probably one reason he's so back lit, to obscure his timing errors.
It's actually the same camera, just zoomed. But definitely the cuts mean it wasn't recorded in one go. But people can often make mistakes and have to redo some parts.
Audio can be cut just like video. Just because it was cut, doesn't mean it wasn't recorded at the same time with the video.
