Does Vortex check subfolders for duplicate files in different mods?

[TheLastEagle1]

Example: 2 texture mods have several identical files. If at least in one mode these files are in a subfolder, then Vortex does not detect an intersection. And if you transfer all the files to the root folder, then Vortex reports the intersection.

Question: should it be so?

Or is there a way to get Vortex to scan subfolders?
