The second Matt Anderson is an exact copy of the original Matt, presumably a time duplicate.

Primeval Resurrected Episode 1.1 (flashback)
Matt has a flashback to when the second Matt appeared and told him to "go back" in episode 5.6, before being interrupted by Jess, who informs him of a new anomaly.
At the end of episode 3, Matt sees his double staring at him from the shadows of the ARC building, but as before he is gone the next second. After this, Matt tells Emily about the second Matt, but she doesn't believe him, and suggests that maybe the anomalies are getting to him.
It is revealed in this episode that the second Matt Anderson is from a different timeline where New Dawn was not stopped, and he explains to Matt that the only reason either of them still exists is because after stopping New Dawn Matt caused the timeline to branch off, splitting the universe into two parallel dimensions, one where New Dawn is stopped, the other where it remains and the Sterile Earth still happens. He also warns Matt of a future anomaly leading to this separate timeline, and that the existence of two universes linked by one anomaly threatens to cause the complete collapse of time and space itself. He tells Matt that his original intention was to get him to go back to stop himself from stopping New Dawn, explaining why in episode 5.6 he told Matt to "go back", but he now thinks a better solution is simply for the ARC team to prepare for this anomaly to appear and stop it before it does. He tells Matt that if his calculations are correct this anomaly will open in exactly two months and 11 days, and the ARC team needs to somehow stop it from opening. If they don't, then everything that ever was, is, or ever will be is doomed to perish.
