The man shows an image he's like to try to emulate, but he's told the image the image is wrong; it's a mistake - there is no value in learning how to reproduce that look. This is a matter of taste, and irrespective of taste, we should support someone wanting to expand his or her skill palette. Pros regularly need to master areas they personally may not be drawn to.
To me this sample shows low contrast in the quarter tones, and as suggested, a blue cast in the shadows. Aside from the blue channel curves adjustment proposed above, it may be that raising both shadow level, black clipping level, and lowering overall contrast will help. One of the traits of haze is that, like fog but to a lesser and different degree, contrast is lowered but to different degrees across the spectrum. The sample offered is probably also split toned, or the equivalent of split tone method. I think the shadows are blue, and the mids and highlight are yellow-orange. I associate this feeling with hot-weather haze.
It's worth mentioning the original exposure was in high-contrast, pretty harsh light. That plays a huge role in the final result too, of course.
