Using $^{31}$P nuclear magnetic resonance (NMR) we investigate the recently discovered presaturation phase in highly frustrated two-dimensional spin system SrZnVO(PO$_4$)$_2$ [F. Landolt et al., Phys. Rev. B 104, 224435 (2021)]. Our data provide two pieces of evidence against presumed spin-nematic character this phase: i) NMR spectra reveal that it hosts a dipolar order and ii) 1/$T_1$ relaxation rate recorded above saturation field can be fitted by sum single-magnon term, exponential gap, critical second-order triple leaving no space for nematic dynamics, characterized double-gap exponential. We explain unexpectedly broad validity simple fit related dynamics.
