I got it wrong, @takkt1 was the person doing the quoting and will have to speak for himself, but my guess is that he didn't intentionally choose to add his supportive sentence in the quoted area.
I'm my case, I'm moving the pictures outside the quote to make them larger. If there's nothing left in the quoted area (because it consisted solely of the image), it won't show, so adding a "(below)" is a reference to the picture, and makes visible the information about who I stole it from. If you click on the little blue upwards-pointing-arrow, it will take you to the original post. That's the doing of the Forum software, not my invention.
