Are you certain that he wasn't with a different group (see also https://twitter.com/ElijahSchaffer/status/1298566712179204096 )? I'm not seeing him in this one (though I could be mistaken): https://mobile.twitter.com/ElijahSchaffer/status/1298506102049591296 , but there is an interview with him in: https://twitter.com/RichieMcGinniss/status/1298657958205820928 (I saw another video, but I can't find it at the moment).

Notice that he has long pants on covering all of his legs, while one of the groups has a different green-shirt guy that has shorts that do not cover the lower parts of the legs.

EDIT:

Never mind, it seems that at least some of his friends were in the given group:
