What does nrfjprog --rbp ALL enable?

[Cla]

My assumption is, that `nrfjprog --rbp ALL` sets APPROTECT to the apropriate non-0xFFFFFFFF value.
But does it additionally also set SECUREAPPROTECT?

I found documentation here, but it did not specify in detail: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_nrf_cltools%2FUG%2Fcltools%2Fnrf_nrfjprogexe_reference.html

Edit: My understanding is, that it does NOT enable erase protection. Is this correct?

Thanks in advance.
