  We present the analysis of two-particle angular correlations using coordinate
systems defined with the conventional beam axis and the event thrust axis, and
propose the latter to be a useful representation for the correlation structure
interpretation in the $e^+ e^-$ collision system. The $e^+ e^-$ collisions to
hadronic final states at center-of-mass energies of $\sqrt{s} = 10.52$ GeV and
$10.58$ GeV are recorded by the Belle detector at KEKB. In this paper, results
on the first dataset are supplementary to the previous Belle publication
arXiv:2201.01694 while the latter one is the first two-particle correlation
measurement at a collision energy on the $\Upsilon(4S)$ resonance and sensitive
to its decay products. Measurements are reported as a function of the
charged-particle multiplicity. Finally, a qualitative understanding of the
correlation structure is discussed using a combination of Monte Carlo
simulations and experimental data.
