Measurements of short-range correlations in exclusive $^4$He$(e,e'pN)$ reactions are analyzed using the Generalized Contact Formalism (GCF). We consider both instant-form and light-cone formulations with AV18 local N2LO(1.0) nucleon-nucleon ($NN$) potentials. find that kinematic distributions, such as reconstructed pair opening angle, recoil neutron momentum distribution, center mass motion, well measured missing energy, all reproduced by GCF calculations. The dependence / $^4$He$(e,e'p)$ cross-section ratios, sensitive to nature $NN$ interaction at short-distacnes, also calculations either formulation. This gives credence scale-separated factorized description short-distance many-body nuclear wave-function.
