At a guess, I'd suggest it's to do with the X36's reduction in frequency from every 30 minutes to hourly, even though the branding only applies to the X35 on 4973, as the locations listed are only served by the X35 and not the X36. Bizarre nevertheless. I'd put it down to some confusion from the vinyl appliers when the bus was being rebranded or some vinyls were being replaced.
That seems a likely explanation - thank you.
Whilst we're with the X35, would it be correct to say this is the only branded route that has never have a refresh in either style or vehicle type since the 2006 'big bang' of route branding. It seems a bit unloved!
