You keep missing the point. The INquisitorial Storm Troopers are their own branch. They're one of those rare formal assets that the Inquisition maintains, like the Grue Knights of Death Watch. If he was an IST he would have been raised in the Progenium, would have started working for the Inquisition from the get go, and never have served with the Gaurd, and thus couldn't really claim to be from a Necromundan Regiment. On the other hand if he was a Storm Trooper that an Inquisitor put through storm Trooper training, then he would simply be a Storm Trooper working with the Inquisition, not an IST. The issue here is that you are mistakning an Inquisitorial Storm Trooper as a "Storm Trooper that works with the Inquisition". I am trying to help you realize that that's inaccurate.
