The point people are making about using GitHub profiles for hiring is that it ignores great developers who don't write code outside of their job (that might be due to other interests, family responsibilities, a second job, whatever). The fact this guy is in a position to write code in his spare time just means he's not in that group, and the fact his open source work on Github specifically landed him a job he wanted kind of proves the point people are making.
