Yup, looks like it. Great work on that. Weird to see the Orange Line routed to Copley, though that does make the most sense for the transfer. (I may have missed it, has the T said if the shuttles are serving Copley or Back Bay proper?)
My understanding is they will serve both. A north bound shuttle will come up Columbus, turn left onto Dartmouth and stop at back bay, continue up Dartmouth and stop again in front of the BPL, then loop around Boylston/Clarendon to catch southbound Back Bay riders at the bus loop before proceeding back down Columbus.
Edit: to this end, as I’ve said before Dartmouth will be closed to general traffic in front of the BPL and will only be open to southbound general traffic between Huntington and Columbus
