He admitted to me he didn't learn about it until about a year ago. Meaning he never used it in his code and he never understood the concept.

He was a python programmer. Typically in python, you shouldn't use recursion anyway.

Recursion isn't very good in Python this is true. I'm not going to judge the guy's skills since I don't know him, but that seems to be a common pitfall that a lot of developers I know find themselves in - they learn a single language or framework and never break out of it.
