so first off, if you are noticed in a crowd but not identified, that might single you out to be pulled from the crowd.
Also if you have a distinctive face paint then your image might be shared more, or just noticed more in the images that are shared to give more opportunities for people to recognize you or to remember your face to be recognized latter.
Also having a distinctive face would make it easier to track in different sets of footage especially when the technique was originally demoed in 2011.
I understand the mechanism you're tracing, but it feels like there's a category error here. Everything you're saying hinges on the circumstantiality of human reaction and interactions, which is extremely hard to model in a credible way and easy to become colored by subjective biases informed by things like TV and movies. Those channels of recognition and reporting that would lead to positive identification, are nebulous idiosyncratic and depend too much on speculation.
It's not to say it wouldn't ever happen, but there's an order of magnitude difference between that and guaranteed positive identification which is what informs the calculated risk.
