The behavior has not changed. The dropdown you are referring to determines how duplicate files are handled (meaning files that have identical content and are identical sizes). If you use Import->Local File, and import a PDF that matches of a PDF in the storage location, you absolutely will still see the dialog asking how you want to handle the conflict. Make sure that Settings->Storage->Create Subdirectory per Song matches what you are expecting, as that setting was switched off by default a little while ago, which causes confusion for some users, as they have some songs in folders, and some not, creating problems when importing new versions of files.
