Hi,
I haven't touched the name of this stop area but simply inherited from a former OSM contributor. Names for stop area relations are currently not rendered anywhere which is why often they are descriptive to help telling them apart. This seems to be the case here as well to easily differentiate in OSM editors which stop area belongs to the upper or lower portion of Stratford. All stop position and station elements in this stop area bear the correct name "Stratford". So not sure if the stop area's name needs amending.
