Most likely that was the circle/district line. It's only one flight of stairs down from Cannon Street and Mansion House. Not sure how many metres, but it isn't far down at all.
Someone managed to run between them actually, leaving the train at Mansion House and catching up to it again at Cannon Street! https://www.youtube.com/watch?v=PH_Z8Ghuq6E
