Question about disabling Mac-Learning

I just got my JNCIA and am working towards my JNCIS, I was going through CBT nuggets and they glossed over the idea of the command on JunOS: "set ethernet-switching-options mac no-mac-learning"

Why would you enable this? Are there any real-world examples you have used this? I tried reading Juniper's website on this, but they don't really explain why they only explain how.

I understand what this does to the device when it is enabled, I am just unfamiliar with reasoning behind the config.
