If a file is supported by more than one application, Mac or even Windows opens it selecting any app they like and also set it as the default app. So whenever you try to open such files, your computer will use the same application to open the app.

For example: If you have a Pages app, as well as Microsoft Word, installed on your Mac, opening MS Word Files (with .doc or .docx extensions) could be a little tricky.
