Listen to the audio - it’s not just a shift upwards. If it was, the audio would till have continuity. It loses all continuity.
That is, in fact, a cut in the video. Some segment of video has been removed.
I listened to the audio. It sounds to me as if it does have continuity. It sounds as if he’s still stepping on leaves as the camera moves around.
It's quite possible that the guy's finger covered the mic port on his phone as he was shifting the camera.
