I really thought that the Order would have seen Durkon's and Redcloak's conversation from the ledge. Then again O-Chul needed a spyglass, so maybe that's why.
The ledge is likely below the bugbear village level.

Anyways, yes! the Order is back! Loving Elan, loving the team.
I'll spitball that maybe the Order will run into a comatose Lien and O-Chul in whatever gate they pick.
