They did mention about using tactics to encourage better communication (with the visual feedback and such), which showed that those efforts led to better team performance; so, for me, that shows good communication creates a good team environment instead of vice versa (since the communication was the variable that was changed during the experiment).
People often forget that communication is a skill that can be honed. Certain behaviors - body language, active/passive, talking versus listening, etc. - can be adjusted to make you a better communicator.
