The way the comics handle prototype interdimensional mirrors-like the one this arc centered around-seems to be that they only function when they're completely intact. In Legends of Equestria, Star Swirl has Rockhoof smash a mirror in order to render it useless, and its only by reassembling every single piece that the Nightmare Knights are able to use it again in that comic. Celestia literally only had a fragment left, presumably meaning that reentering mirror Equestria wouldn't be possible-at least not using it.
