Warscroll Battalion: Ruinbringer question/understanding

[PhantomBaz]

Hi,

I'm thinking of try out the Runibringer warscroll battelion. I what to get a clear picture of how this works, if my understanding of it is correct...

"After any charges have been made, any energy units within 3" of any models from the battalion are crushed under the weight of the charge and suffer D3 mortal wounds,..." (enemy 10+ suffer D6)
 
So from my understanding of this is, that if i have two units of Chaos knights hitting 1 enemy unit that that enemy unit then suffers two set of D3/D6 MW from each unit of knights (and any enemy unit within 3").

Thanks for the help,
