Partly. The part that ends at 0:25 IS edited by uploader, but the rest of this is edited by Gesaffelstein THEN re-edited by Justice and used in some of their 2012-2013 sets.
Ce mixage est un chef d'oeuvre... Sûr qu'il garde leurs meilleurs morceaux pour la gloire car c'est exactement le genre d'énorme son qui réveille n'importe quelle foule!
That's a dj set, and the the track is not fast enough for that, so they sped it up. Plus this was played six months ago, Justice said that the track did not even have a name at that point. The vocals are on the Glow version, it's just hard to hear them well. He probably gave them this rough version as they liked it, but it is merely a demo (even though it's already amazing)
im convinced that justice or gesaffelstein made this remix of pump because the one on glow is much more laggy and this one has a differnt build and cut up vocals
