Question about this shot in the movie "The Revenant"

So, i was watching "The Revenant" from 2015, and this shot stuck out to me. Context: In the picture above, Tom Hardy is holding Will Poulter at gunpoint, he shoots but there is no powder inside so Poulter survives. The shot then moves to tom Hardy as he leaves the scene. Then we get a cut to presumably the face of poulter again? But now he is covered in snow all of a sudden, laying on a snowy surface, while previously there was barely any snow in the picture.

The following scene takes place in a lot snowier location with Diaprio and his son lying on the ground, but it can't really be Dicaprio's son either because he looks nothing like that.

So, Am i just tripping or is this a continuity/production error?
