DefaultCurrentThreadCulture Remark is Ambiguous

On this page, https://learn.microsoft.com/en-us/dotnet/api/system.globalization.cultureinfo.defaultthreadcurrentculture?redirectedfrom=MSDN&view=net-7.0#remarks, there is a remark which states the following:

`If you have not explicitly set the culture of any existing threads executing in an application domain, setting the [DefaultThreadCurrentCulture](https://learn.microsoft.com/en-us/dotnet/api/system.globalization.cultureinfo.defaultthreadcurrentculture?view=net-7.0) property also changes the culture of these threads. However, if these threads execute in another application domain, their culture is defined by the [DefaultThreadCurrentCulture](https://learn.microsoft.com/en-us/dotnet/api/system.globalization.cultureinfo.defaultthreadcurrentculture?view=net-7.0) property in that application domain or, if no default value is defined, by the default system culture.`

I think the typo(s) make this a bit unclear, is it:

If
1. These threads execute in another application domain
2. Their culture is defined by the [DefaultThreadCurrentCulture] property
3. No default value is defined by the default system culture

Then
DefaultThreadCurrentCulture won't take effect, so you need to set CurrentUICulture? I think it could be made a bit more clear how 2 and 3 are different, as well as how is it possible that the DefaultThreadCurrentCulture culture doesn't work if it is defined by DefaultThreadCurrentCulture?

Leggere la pagina API collegata di CultureInfo.DefaultThreadCurrentCulture e la relativa sezione Remarks, quindi confrontare la documentazione collegata di DefaultThreadCurrentCulture. Chiarire la distinzione tra una cultura del thread impostata esplicitamente, una cultura predefinita del dominio applicativo e la cultura di sistema. Il lavoro è completato quando la nota spiega senza ambiguità quale cultura si applica in ciascun caso.
