The main purpose is not to store the notes, but to create a way to easily hand the note as a piece of paper.
When showing the note screen position will be locked on either Landscape or portrait, furthermore, the screen can be set to not turn off, check all of this on the settings page.
Ideal scenarios of use: you want to remain silent, you want to be discreet, you can't talk, you are too lazy to say a long bank account number, you are surrounded by people who don't hear well.
