If you're worried about batwings, you need to re-examine your priorities.
If you're using the factory whips, you do NOT get to go from fixture to fixture; the wire isn't sized for that.
Otherwise, you read correctly, the 6ft whips need no support. Indeed, it might be hard to remove the tiles if the whips are secured.
What you attach the batwings to is another issue, as it appears that you can no longer use the wires that hold the ceiling up. Considering how 'busy' ceiling space has become, hanging more support wires is sure to be fun.
