A citation, please? The only video that I know of is [1].
[2] is my best mock up of the only video I have. I'm am not an expert, but my best read of that is that the RWSL is maybe? green to the taxiway¹ traffic, so, to me, the actual status of the RWSL at the time of the incident is "unknown"; that seems like something I should wait for the NTSB report, or at least someone with expert knowledge on. But your claims doesn't jive with the evidence I have, so that's what makes me ask for a citation.

¹but I think there are a number of problems with my own interpretation: I could be wrong about which lights are which; I am using the near-side lights, not the lights on the side the truck is entering from, and assuming them to be symmetrical (though what little I can see of the far side does seem to align with the near side); some of the lights I think are RWSLs & not RGLs look downright yellow, but that could be a property of the low quality of the video; there's the rather large problem of the plane on the runway that must then be explained.
