A Multi-particle state, wave-function with fewer zeros interpretation

Hi , reading some notes on quantum hall effect, a comparison between Moore-Read wavefunction and Laughlin wavefunction is ' the moore-read state has fewer zeros suggesting the particles are more densely packed'

Just confused with understanding why fewer zeros means the particles are more densely packed- all I can think to do this, amplitude of the wave=function gives the probability (once integrating over spatial coordinates) the probability of finding particles within a region,so if there's less zeros, this will be larger? or is this reasoning totally off?

many thanks
