CUBEMX RCC settings unfunction

I am using STM32CUBE V1.0 Version 4.24.0

I am using STM32F107VC.

In the RCC settings

For the purpose to know the what code has been modified.

I use WinMerge to compare the outputs.

I enable the [1] (mark by yellow) and [3] (mark by yellow) ♯♯♯, then generate a project A.

Then I disable [1] and [3], then generate another project B

after comparing project A and B... 

I found 

[1] and [3]  doesn't do any thing to the code generation.

So, the [1] and [3] are useless?
