Looks like the same driver to me!
Not every Sapphire shift will be a full shift on Sapphire routes - there's a few of the Stockton ones that do Middlesbrough town routes as well as 5s (not to mention the Stockton Sapphire rota also has the S1 on Saturdays meaning a full day working on Stockton routes). Likely some Durham shifts are the same (despite them have more Sapphire routes than any other depot).
