Dynamic Animation Replacer and Logical Operations

[Helsong55]

Hi, hope someone could explain to me how DAR handle logical operations. Reading the description of the mod it says that it handle operations the same way that Creation Kit does but I don't know how CK handles them and looking around internet I could't find a good answer, just some people explaining what logical operations are, not how they are handled inside CK. The mod then continued by providing an example:

(A || B) && C
=A || B && C
A OR
B AND
C
 

but that told me nothing. Hope someone could expain to me how the operations are handled,

I just want to modify a small idle that follows the next logic operation (A OR B) AND NOT(C OR D)
