Recruiter here. I've seen GitHub used in interviews where the interviewer may look at the code before the interview, and then bring up the repo during the interview to discuss it. This is usually to challenge why certain decisions were made, what could have been done differently, etc.
It isn't much different than how a conversation would go after a live coding exercise to review the work, with the exception that the candidate in the case of a prior GitHub work will have had the advantage to clean things up and perhaps has gone through several iterations already.
