Basic Reanimation question

[Seahawk]

I feel dumb for asking, but...

 

So I was playing a fellow yesterday, and his way of playing RP was that a unit completes all of its shooting/chopping before rolling RP. For example:

 

Squad with 2 plasma, 8 bolters. He'd roll the bolters, score kills, then the plasma, score kills, then I'd finally roll RP.

 

I thought it was for each attack, so he'd roll bolters, then I'd get RP, then he'd roll plasma, then I'd get RP again.

 

Which is it?

The rule says, "after it [enemy unit] completes its attacks" roll RP. So it is after all attacks have been resolved for the unit.
