It does look like BER damage, but it's kinda high up on the pod; BER would normally be around the midpoint or 3/4 of the way from where it is in that pic to the blossom end of the pod.
I have had a bunch of that exact situation with pods this year - BER-looking damage that's more of a mid-pepper rot than a blossom end rot, but I think it is probably BER.
