Depends on the effect you want. You can do lots of cool/cheesy tricks by moving the camera, like putting the sky from a different place into a different photo, or seeing stars inside a person silhouette. That’s all double exposure, regardless if you like or consider it “proper technique”.
I was thinking about HDR photography where you take multiple pictures of the same scene with different expoures and combine the best parts of each for a picture with a high dynamic range. This evidently wasn’t the case here.
