Why it makes no sense? It is better, isn't it? The wiring is original from developer and I know it is a ring because I checked it myself. There is no voltage problem and it is just normal semi-D house size in Malaysia to concern about voltage drop in wire. I did extend a bit at the back of the house and I pulled another big cable from main DB to another DB I added at the back of the house to supply power for kitchen, air-cond and heaters to rooms/bathrooms at the back of the house. The kitchen is electrical hob, hood and garbage disposer. Developer only provide power points for air-cond and heater to master bedroom only. 
My friend and I got cables laid down during renovation work.
It makes no sense to me because it increases cost, increases complexity, increases installation work, increases points of failure, increases the chance of being done wrong (see conduit fill, proper torque for terminals, number of wires into a terminal) and is so unnecessary to do with 4 mm² at 32 A. There's also no benefit of increased current carrying capacity, as your MCB is C32 anyway. And you also say that the area is not that large, so no reason to do it for voltage drop in the wires. My friend and I got cables laid down during renovation work.I contend that a simpler system that does the job properly is always better than a complex system.
As for benefit, well it is a fully redundant system since you say the wires are 4 mm². Is this "better"?.... if you think it is better then it is.
