I think he's saying that he (GlenTheMachine) is Glen Henshaw, "space roboticist", and (understandably) was a bit excited that a somewhat famous document contains a "law" bearing his name as attribution was posted by this water cooler. A way to get some minor attention for it in a comment thread full of like-minded users, and probably offer a genuine (and also maybe coy/tongue-in-cheek) offer to answer questions about that specific line item law.

I like that he waved from the crowd in this way, if only for the "huh. Small world" moment I had reading his comment.
