im very glad you enjoyed the remix!!
you're half correct with your guess. i pretty much just introduced wider sounds during that section. the sounds that i used also had a bit more of a high end to them compared to the ones before. bringing those high frequencies can create a wide-sounding facade. meaning that its not necessarily wider than the sounds before, but it tricks the ears in a way to think that things are now wider and bigger. also reverse fx and volume/eq automation can create that smooth explosion kind of effect.
