Studio didn't detect duplicate screen when created

I created the same screen in two locations by mistake and the Studio 6.10 (latest) didn’t detect it at the time of creation. Pls see below the image.

You can create screens with the same file names in different packages. Only screen id should be unique.

I see. Then this is something new that I didn;t notice earlier! Thanks Konstantin, for clarifying.
