Just a guess, but the way the Buck ambidextrous thumbstuds, I have had apart, attach, is one side has a splined post, and the other side has the female receptacle for the splined post. the post goes through a smooth bore hole in the blade, and snugs up into the female receptacle on the other stud
That stud looks like all the others I have, and I would suspect it is the same.
Plus there are screws for a lefty clip location, so it makes sense for a lefty stud to be there too.
Once again, just a guess.
