Apple's refurb stuff generally undergoes a more stringent QA process than their factory stuff (in fact a lot of the refurb units are returns that were never used, but are still checked). There might be some visible differences if repairs are required, but the quality should generally be as-good or better. The iPad in this video is either an anomaly or, more likely, not an unaltered refurb from Apple.
