Duplicate assembly in whitelistFixed

Sorry for my bad English
I am a programmer and I am venturing into making plugins for RUST and as usual my not to commit bugs I have been studying the code of Oxide, to be able to understand the calls, Hooks and etc ... then I came across something that I found strange, it doesn’t affect Oxide itself but it seems to me just a flaw in a call to something to use in plugin and ended up just repeating the previous one, I checked the previous versions of Oxide and there really is no such repetition but an indication for future calls, to put it simply, is it correct what I post below or was it to be a new call for new plugins to use and just typed?

RustExtension.cs file

        public override string[] WhitelistAssemblies => new[]
        {
            "Assembly-CSharp", "Assembly-CSharp-firstpass", "DestMath", "Facepunch.Network", "Facepunch.System", "Facepunch.UnityEngine", "mscorlib",  "Oxide.Core", "Oxide.Rust",
            "RustBuild", "Rust.Data", "Rust.Global", "Rust.Localization","Rust.Localization", "Rust.Platform.Common", "Rust.Platform.Steam", "System", "System.Core", "UnityEngine"
        };

dual "Rust.Localization","Rust.Localization" in code

That list has nothing to do with plugin calls or hooks, it is simply a list of DLLs that are allowed to be used by plugins that are referenced already. The duplication there is not an issue.
Yes, I noticed that it does not affect the plugins and that it is a call to something and I am grateful to Wulf for explaining what it is for, if you want you can delete this message
It isn't a call to anything, it is just a list for Oxide to use when compiling plugins.
Okay, again I apologize for my terrible English and ends up giving problems.
When I wrote the call, I wanted to say a use for something, like you Wulf already explained what it does.
When I made this post I commented that I just found it strange to be duplicated that I indicated.
The fact that I am even seeing and reading about Oxide where I came across this is that avoiding doing routines that of course, skillfully you, Umod team, have already worked and made the calls to the RUST server, again thank you for having me responded quickly.
No worries, glad it resolved your questions and concerns. :)
say i wanted to remove somthing for testing so i can grab a wav file from a folder where can i edit the list?

Disable the sandbox by putting oxide.disable-sandbox in your Managed directory.
Thank you.

figured it out.
if (File.Exists(Path.Combine(Interface.Oxide.ExtensionDirectory, "oxide.disable-sandbox")))
            {
                Interface.Oxide.LogWarning($"{Path.Combine(Interface.Oxide.ExtensionDirectory, "oxide.disable-sandbox")} found, disabling security sandbox.  Potentially dangerous APIs and methods are now allowed inside plugins.");
                CSharpExtension.SandboxEnabled = false;​
