Having not seen it, I cannot tell whether it was samba or not, but do not see any reason why it could not be. Hyperventilation paradoxically starves the brain of oxygen, due to the mentioned stronger O2 binding to hemoglobin, and due to the contraction of the carotid arteries (and also the remaining blood vessels in brain). Physiologically the mechanism of a hypoxic and hypocapnic blackouts are very similar. Blackouts after hyperventilating are quite common, so I see really no reason why hyperventilation and hence the consequent hypoxia in brain could not cause LMC.
