Using 4{pi} data from the Bevalac streamer chamber, we study azimuthal correlations for fragment pairs and higher-order multiplets. We point out that previous studies of sideward flow have not ruled out the possibility that the effect is dominated by a small number of correlated fragments in each event, as opposed to being a collective motion to which most or all fragments contribute. Based on a simulation, we infer that more than 70% of the forward-going fragments from collisions of Ar on Pb at 0.4{ital A} GeV carry a component of the collective motion.
