I've done quite a bit of jumping from helicopters; it's nearly always with some slow forward speed (circa 60kts).
However, 2000ft is really too low for safe jumping with a skydiving rig; so they must be using either base rigs or static line as noted above. Base rigs don't have sliders and open immediately, whereas skydiving rigs open more gradually ("snivel") for up to around 500 before fully opened.
