Correct, that Retaliator is just being primed and fired in quick succession. Still, it must be said that the ROF is impressive.

"Slam-fire" technically means that you can hold down the trigger and fire after each complete priming cycle. It cuts down the required movements from three per shot to two, saving a fraction of a second.
