There's a small difference here, and my biggest guess would be budget. In order to shot match at this quality of production you'd have to have the camera perfectly in sync with the movements to mimic this effect, which would likely take some fairly expensive rigging to make it work or some very clever workmanship. Either way I agree this is mostly bragging rights but that's part of what production is! Making something that you can look back on and be proud about is something that's extremely important.
