In the comment thread at Byzantine Texas this has been identified as coming from the Episcopal Diocese of Southern Ohio - Youth and Summer Camp Program.
So no, this was not a Catholic thing. I really should have had the Episcopalians at the top of my suspect list.
The Novus Ordo and the Episcopalian services aren't all that far off from each other, so I completely get the confusion.
According to commenters at Fr. Z’s blog: Episcopal Diocese of Southern Ohio summer youth camp, London, Ohio.
Thanks for the update, I was concerned. A lot less to be concerned about IMO, since the Blessed Sacrament wasn’t part of that ceremony. Just a symbol.
