Which atlas is the single sprite referenced from multiple atlases to select?

For example, I have a folder for the UI sprites per menu, and I create a sprite atlas for each folder.
I don't want to duplicate the physical files of the UI sprites, so I decided to create a common folder.

texture/title_menu/titlemenu.spriteatlas

texture/select_menu/selectmenu.spriteatlas

These two atlases have references to several files in the texture/common folder.

I understand that the sprite file reference is automatically switched to a reference to the atlas at build time,
but If I access the sprites contained in both atlases in the common folder, which atlas will be referenced? Is it random?
