why paddle latch has 2 cylinders? If combine 2 into 1 will be useful?

Hi everyone,

I have a question about the Paddle lock, I want to know why paddle lock has 2 cylinders? Does anyone think about to combine it into one? If combine it into one cylinder will be safer?

As I know one cylinder control paddle, if you lock it, the paddle can’t be opened. Another one control deadbolt and you also can lock it by the red bar on the other side.
I’m wondering if we make those combine as one cylinder which can open paddle and deadbolt with a snack key cut cylinder. Anyone have an idea about it.
