Probably because he wants to use a translation patch on it. Some translation groups release self-executing patches that don't work if the iso has a different checksum. Only contradiction is, the game was just released. If there's a translation patch, it would just be a menu translation and not story translation, which is not really worth the time in my case.
Anyway, if you really can't find it on English sites, then do the opposite. There are a lot of release groups in foreign countries too. Of course, the rules say I can't tell you where to go, so...
