Could be that originally it was two separate circuits.
At some point, one of the switches has been removed.
 
Don’t know the layout,
Could be it was designed so it could be split into 2 separate zones with a partition?

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.
 
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 like your thinking - it's got to be something like this surely, but the circuit is run in 2.5mm which for a lighting circuit that has a furthest point about 30 metres from the DB, doesn't sound like it would struggle.
 
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? :D
 
I think it is an attempt at what Lucien Nunes described at his #17 to obtain more even brightness from all the fittings in this large assembly hall - but the electrician only wired it 1/3 correctly - for fittings 1-3. He should have taken the second N to fitting 6 and 4-6 should take their line by a connection from fitting 1 to fitting 4 (or other permutations which arrive at a similar effect).
