To help me understand more can you confirm that the green/white line around

Yes, those are the morning-peak-only anti-clockwise services run by
Southern to London Bridge.

IIRC there are some clockwise ones in the evening peak. I can't

anticlockwise ones in the evening, but they should all be listed in
the FCC .pdf timetables linked to earlier.
