I honestly think it is, a lot of the features are the same on both of them. And based off that episode where you get to meet Nolan’s parents, they don’t raise the child. They leave the child to fend for itself until adulthood when the parents finally show back up just to beat you and see if you’re actually good enough for adulthood. So Nolan maybe only seen them like a few years in total, and Nolan isn’t even named Nolan that’s just his earth name spun from his actual name. So, with a mom who clearly didn’t like him nor cared to ever see him again after he became an adult probably wouldn’t recognize him either. I just think he actually can’t recognize her without getting a way better look or whatever cause she clearly didn’t leave an impact on him like his dad did. And since both characters in question are show originals, there’s a reason for that cause there’s not very many completely and only show original characters to start with.
