  The azimuthal cumulants, $c_2\{2\}$ and $c_2\{4\}$, originating from the
global conservation of transverse momentum in the presence of hydro-like
elliptic flow are calculated. We observe the sign change of $c_2\{4\}$ for
small number of produced particles. This is in a qualitative agreement with the
recent ATLAS measurement of multi-particle azimuthal correlations with the
subevent cumulant method.
