You may or may not be aware, the parent comment you're replying to, is a reference to a certain President's (idiotic, unhelpful, and uninformed) tweet at the time.
As always it's important to /s sarcastic comments online because text does not convey sarcasm well without something like /s or the new cAmEl CaSe which does really well.
It's when the mocking and sarcasm is more important than the message. A lot of times it's used to just parrot back whatever the person you're mocking said anyways so readability doesn't have to be perfect.
Thanks for providing a real explanation though.
