I noticed that as well. But that's not the only mistake in the article. The 8K Monstro does not share a sensor with the Helium. They might have the same resolution, but are two completely different sizes, ergo they are not the same sensor or even sensor architecture.
But wait, that's not all! In the Gemeni section, he equates "low distortion" and low light. Ummm, did you mean "noise?"
Finally, the headline has nothing to do with the content. Writing a few vague specs and a couple sentences on each camera doesn't provide very much insight into helping someone decide "which RED cinema camera is right for you?" This site has had some generally useful articles, but this one is all just filler.
