Could be that originally it was two separate circuits.
At some point, one of the switches has been removed.
Nah, big assembly hall, always been like that since day dot. I'd surely expect to see spare line conductors in the trunking though if they'd altered the circuit over the years. I'm not writing you off by the way, I'd love someone to tell me the answer but me and 4 council sparks couldn't come up with it.Don’t know the layout,
Could be it was designed so it could be split into 2 separate zones with a partition?
Maybe they were just too tight on voltage drop, decided to spread the load between two cables but only bothered on the long straight run of neutral rather than doing the same with the switched line?
I've wired circuits in a similar fashion once or twice with duplicated cables for no apparent reason.
What actually happened is that with two of us working on the job we both thought the other was pulling a different circuit/cable but actually we were doing the same as each other. Usually when we're working long into the night to get a job back on schedule.
Have you ever done it with 5 circuits, in mirror of each other, by total accident?
