Default lighting circuit help

I replaced a standard light pendant and although everything works I am
slightly confused about the light circuit. The celing rose consists of
three separate cables (one double core, the other two both single
core). One of the double core cables goes to the live junction in the
ceiling rose the other to the earth connection. Both single core
cables (twisted together) go to one of the neutral junction terminals
(nothing goes into the loop section of the ceiling rose).

The only idea I came up with is that the neutral loops round all the
ceiling roses and the same thing happens on the live side in the
switches (which in the room where I replaced the pendant also has
three separate wires going into the switch). So I have a ring lighting
circuit?

But again I am not sure so any suggestions are welcome

You don't get ring lighting circuits, except for some industrial
situations.
What you have is the neutral feeding all of the lighting points in a
radial configuration.
The lives loop around all of the switches in a radial configuration.
Then from each switch a single live switch wire is taken to the light
point.
The three seperate wires in your switch, (assuming you have 1 light
point in the room in question), would be - 2x live feed and 1x live
switch wire.
The last light on the circuit would have 1x neutral in the light point
and 2x live in the switch, (1x feed and 1x switchwire).
