[Action] Simplified Rapid Fire

I’m about to start a new Action campaign and was going over rules so that I’m ready for it.

However I’m a little confused on the Simplified Rapid Fire Rules for Total Number of Targets in Action 2 pg 36.
It states for guns with RoF 2-4 hitting multiple targets there are -6 for two targets, at -6 for each additional target. Halved for Gunslinger. (Alright, no big deal. I get it. But then comes the next sentence) “If the weapon has RoF 5+…there’s no special penalty.”

What does that mean?
Example: Gunslingers Roy and Steve are hosing down enemies. Roy shoots a pistol with RoF 3 and Steve shoots a SAW with RoF 20! Roy shoots at three different mooks. His penalties from Total Number of Targets is -6. Steve sees that this is a good idea and sprays down three other mooks.
Since Steve is firing an RoF 5+ gun he has “no special penalty” but what is the total penalty for Steve firing at multiple targets?
1) Is it -6, just like Roy? or…
2) Is it 0? Because he’s shooting loads of bullets

I’m leaning more towards option 1 but I can see the argument for option 2.
