Wiping down with IPA is used when you're correcting paint with the like of a DA or rotary etc and polishing compounds like Megs 105 & 205 etc. Polish residue & oils can be left on the panel & 'fill' swirls effectively giving the effect of having better correction.
Ceramic sealants and quite a few liquid/paste sealants require the paintwork to be 'bare' for application so IPA is a great way to prep it.
