Why do people keep adding this to their comments? Are they checking notes? Why do they feel the need to point it out if they are? Why are they saying they are if they aren’t? It’s like me adding “scratching head” to my comment, which I just did, but I have no idea why that adds anything to the conversation.
I believe it came from the popularity of Jon Stewart who often uses it as a joke catch phrase.

People picked up on it and use it to imitate this style.
Personally, I initially saw a version of it in Sluggy Freelance.
And every courtroom drama, like checks notes My Cousin Vinny.
I looked at the script and it’s not in My Cousin Vinny. Is it ad-libbed somewhere?
Check the notes.
