Default Wiring Ring mains to MCBs in consumer units

In my flat I've discovered that each end of the two socket ring mains
go back to separate MCBs. I've tested this by using a multimeter,
turning off an MCB and still getting 240V on the live terminal (i.e
I've got to switch off 2 MCBs to turn off the circuit). To clarify I
have 2 32A MCBs per ring main, (4 in total). I would have thought
that both ends of the ring main should go back to the same MCB (i.e.
two wires into the MCB) The way it's been wired, each individual live
wire goes back to an individual MCB.

Have I got 2 MCBs too many in my fusebox. I think its wired
incorrectly am I right


Thanks.
