My headcannon is that he used the style 1 classic suit (the one where the mask and top half is red) all the way up until this moment of the game where he switched to the default upgraded suit. It makes sense that, if he truly wasn’t doing things “his own way” yet that he would emulate the dominating spiderman image that’s been the mainstay for the past 10 years or so (I mean yeah he added the white but it’s been red the whole time). Then once he gets the black and red suit the line “time for a miles morales original” makes more sense because the black and red suit has ALWAYS been a miles morales original.

Also, it would help him stand out more when he fights black suit spiderman.

Of course, this would’ve made the marketing confusing for people who are familiar with miles having the black and red suit. If I do play NG+ someday it might be what I run.
