So according to the WD with the Kataphron Battle Servitors, the Torsion Cannon (24", S8, AP1 - Heavy 1, Gravitic Contortion), the Gravitic Contortion rule reads as follows:

-Each time a non-vehicle model suffers an unsaved Wound from this weapon, it loses D3 Wounds instead of only 1. Each time a vehicle model suffers a penetrating hit from this weapon, it loses D3 Hull Points instead of only 1.

So my question is, if a non-vehicle model in a unit, like a Space Marine in a tactical squad, suffers an unsaved wound, and then takes, let's say, 3 wounds from this weapon, do those other wounds carry over into the rest of the squad, or are they only suffered by that one model within the unit?
