Hmm! It does look still like him up until the point when you see his hair in profile at the end and then it looks too long for Elijah. When I saw the pics in your previous post I was 90% certain it was him but now I'm less so even though the slight figure, dark hair and arms do look like his. The shirt is interesting in that if that is Elijah, I have never seen him wear it before or since and he does wear clothes repeatedly once he likes them. If he turns up wearing it sometime soon, we'll know but I am beginning to think the guy in the footage could just be a look-a-like technician.
