Pedantic answer: we don't know.
Reprimanding normal users for bad behaviour might take place in public or in private chats/messages.
Reprimanding moderators for bad behaviour would usually take place in private chats or emails.
Reprimanding Community Managers ... I don't know where that happens, it's above my pay grade. Maybe in company meetings? Not in front of volunteer moderators or community members, that's for sure. So technically we don't know whether Shog9 was reprimanded or not, because we wouldn't have seen it anyway.
Practical answer: almost certainly not.
Use of swear words is, in itself, not cause for reprimand for anyone. Some chatrooms ban swearing, but Mos Eisley was never one of them. Swearing at someone, or in an offensive way, is never acceptable, but that wasn't what was happening here. So I see no reason why Shog9 would need to be reprimanded for his use for bad language in this context.
Context is, of course, important. There was a lot more going on here than that single swear word, or even that single conversation. For one thing, Shog9's outburst marked the termination of a chatroom which had caused a lot of headaches for multiple SE employees; when his colleagues became aware of what he'd done, I suspect their reaction was more along the lines of "thank God we don't have to worry about that room any more" than "oh no, he said a swear, we should reprimand him". For another thing, more problematic than saying "shit" was his renaming of the room to "The SciFi / Valorum / Himarm molestation room"; he himself thought better of this and changed it to "Valorum / Himarm poisoned this room; it is defunct" an hour later, and after some private discussion another CM changed it to "Poisoned room; it is defunct" a fortnight later. Whether any "reprimanding" went on around that is, again, something we don't and can't know. But I'd say it's still highly unlikely: at least from the company's point of view, Shog9 is not a community member throwing around random swearwords, but a company employee doing his job, and any apparent lack of professionalism was probably excused on the grounds that he (and other employees) had had to deal with a lot of shit relating to this room in particular and had simply had enough of it.
